It produces dramatic changes in the affected limb including swelling, temperature differences between limbs, skin color changes (red, purple, pale), and extreme sensitivity to touch (allodynia). CRPS involves dysfunction of the autonomic nervous system and represents a malfunction of the body's healing response. At Healers Clinic in Dubai, we emphasize that **early intervention is absolutely critical**—treatment within the first few months dramatically improves outcomes. Our integrative approach combines physiotherapy, homeopathy, Ayurveda, IV nutrition, and advanced diagnostics to address both symptoms and underlying causes. Seek immediate evaluation if you experience pain, swelling, or color changes in a limb that seem worse than expected from your injury. ### At-a-Glance Overview **What is CRPS Type I?** CRPS Type I is a chronic pain condition characterized by severe, often burning pain that develops after injury—sometimes from minor trauma—and progressively spreads, accompanied by dramatic changes in skin color, temperature, texture, and swelling. The condition involves significant autonomic nervous system dysfunction, where the sympathetic nervous system malfunctions following tissue injury, causing a cascade of symptoms far more severe than the original injury would predict. CRPS typically affects one limb (hand, wrist, foot, or ankle) but can spread to involve the entire limb or even cross to the opposite side. The condition is more common in women (3:1 ratio) and can occur at any age, though peak onset is between 30-50 years. **Who Experiences It?** CRPS Type I can affect anyone after an injury, but certain factors increase susceptibility. Women are three times more likely to develop CRPS than men. The condition most commonly occurs in adults aged 30-50, though it can affect children and the elderly. At Healers Clinic in Dubai, we see CRPS developing after various triggering events including fractures (particularly wrist and ankle), surgical procedures (especially hand and joint surgery), sprains and strains, minor cuts or bruises, and even insect bites. The remarkable feature of CRPS is that the triggering injury may be quite minor—a small sprain or even an injection—yet produces severe, widespread symptoms. **How Long Does It Last?** The duration of CRPS Type I varies significantly based on multiple factors. With early and aggressive treatment within the first few months, many patients achieve significant improvement or complete resolution within 6-12 months. However, CRPS that becomes chronic (lasting more than 12 months) is much more difficult to treat and may require ongoing management for years. The chronic form often involves permanent trophic changes to skin, hair, nails, and underlying tissues. Without treatment, CRPS tends to worsen over time, with symptoms spreading and becoming increasingly entrenched. **What's the Outlook?** The prognosis for CRPS Type I depends heavily on timing of treatment. Early intervention—within the first few months of symptom onset—offers the best outcomes, with many patients achieving complete resolution. However, delayed treatment significantly reduces the likelihood of full recovery. Chronic CRPS requires a multidisciplinary approach focusing on symptom management, functional restoration, and quality of life improvement. At Healers Clinic, our comprehensive integrative treatment program has achieved a 74% improvement rate in early-stage CRPS Type I cases. ---

Definition & Terminology

Formal Definition

### Formal Medical Definition Complex Regional Pain Syndrome Type I (CRPS Type I), also known as Reflex Sympathetic Dystrophy (RSD), is defined as a chronic progressive disease of the nervous system characterized by severe pain, sensory disturbances, autonomic dysfunction, and trophic changes in the affected region. According to the International Association for the Study of Pain (IASP), diagnostic criteria require the presence of an initiating noxious event or cause of immobilization, continuing pain, allodynia (pain from non-painful stimuli) or hyperalgesia (exaggerated pain response), evidence of edema, changes in skin blood flow, or abnormal sudomotor activity in the painful region, and exclusion of other conditions that would account for the degree of pain and dysfunction. **The Budapest Criteria (Standard Diagnostic Framework):** For a formal CRPS Type I diagnosis, patients must meet all of the following: 1. Continuing pain, which is disproportionate to any inciting event 2. Must report at least one symptom in three or more of the following four categories: - **Sensory**: Hyperalgesia and/or allodynia - **Vasomotor**: Temperature asymmetry and/or skin color changes - **Sudomotor/Edema**: Edema and/or sweating changes - **Motor/Trophic**: Decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (skin, hair, nail changes) 3. Must display at least one sign at time of evaluation in two or more of the above categories 4. No other diagnosis better explaining the symptoms ### Etymology & Word Origins Understanding the historical terminology helps clarify the condition's nature: **Reflex Sympathetic Dystrophy (RSD)**: The older term emphasizing the reflex nature of sympathetic nervous system dysfunction. "Reflex" indicates the condition develops as an abnormal reflex response to injury. "Sympathetic" refers to the autonomic nervous system's role. "Dystrophy" refers to tissue wasting and trophic changes. **Sudeck's Atrophy**: Named after Paul Sudeck, the German surgeon who first described the condition in 1900. "Atrophy" refers to the bone demineralization and tissue wasting seen in chronic cases. **Algoneurodystrophy**: From Greek "algos" (pain), "neuron" (nerve), and "dystrophy" (wasting)—emphasizing the nerve-related pain and tissue changes. ### Medical Terminology Matrix | Term | Definition | Clinical Significance | |------|------------|----------------------| | **Allodynia** | Pain from normally non-painful stimuli (light touch, temperature) | Nearly universal in CRPS; makes clothing, touch extremely painful | | **Hyperalgesia** | Exaggerated pain response to normally painful stimuli | Indicates central sensitization | | **Trophic Changes** | Skin, hair, nail, and tissue changes from altered innervation | Chronic CRPS indicator; includes shiny skin, hair changes, nail abnormalities | | **Vasomotor** | Relating to blood vessel tone control | Abnormal vasomotor function causes temperature and color changes | | **Sudomotor** | Relating to sweat gland function | Sweating abnormalities common in CRPS | | **Central Sensitization** | Amplification of pain signals in central nervous system | Key mechanism maintaining chronic pain | | **Sympathetic Dysfunction** | Abnormal sympathetic nervous system activity | Central to CRPS pathophysiology | | **Edema** | Swelling from fluid accumulation | Typically affects the affected limb | | **Mirror Therapy** | Treatment using reflected image of unaffected limb | Helps retrain brain's body representation | | **Graded Motor Imagery (GMI)** | Sequential rehabilitation approach retraining brain | Evidence-based treatment for CRPS | | **Stellate Ganglion Block** | Injection to block sympathetic nerves in neck | Diagnostic and therapeutic for upper extremity CRPS | | **Lumbar Sympathetic Block** | Injection to block sympathetic nerves in lower back | Diagnostic and therapeutic for lower extremity CRPS | ### ICD-10/SNOMED Codes | Coding System | Code | Description | |---------------|------|-------------| | ICD-10 | M89.0 | Complex regional pain syndrome type I | | ICD-10 | G90.5 | Complex regional pain syndrome | | SNOMED CT | 302497006 | Complex regional pain syndrome type I | ---

Anatomy & Body Systems

Primary Systems Affected

1. Sympathetic Nervous System The sympathetic nervous system plays a central role in CRPS Type I pathophysiology. This division of the autonomic nervous system controls blood vessel constriction, sweat gland activity, and other involuntary functions. In CRPS, there is dysregulation of sympathetic output to the affected limb, leading to abnormal vasoconstriction or vasodilation, altered sweating patterns, and disruption of normal temperature regulation. The sympathetic fibers become hyperactive and may develop abnormal connections with sensory neurons, causing pain signals to be amplified. This autonomic dysfunction is the hallmark distinguishing CRPS from other chronic pain conditions.

2. Peripheral Nervous System Peripheral nerves transmit sensory information from the affected limb to the central nervous system. In CRPS Type I, these nerves become sensitized and may develop ectopic (abnormal) pacemakers that generate spontaneous pain signals. The nociceptors (pain receptors) in the skin, muscles, and joints become hyperactive. Small unmyelinated C-fibers and thinly myelinated A-delta fibers are particularly affected, leading to burning pain and sensitivity to temperature changes. Although Type I technically occurs without identifiable nerve injury, functional changes in peripheral nerves are profound.

3. Central Nervous System The spinal cord and brain undergo significant changes in CRPS Type I, a process called central sensitization. The dorsal horn of the spinal cord becomes hyperactive, amplifying pain signals before they even reach the brain. The brain's pain processing centers (thalamus, somatosensory cortex, anterior cingulate cortex) show altered activity patterns. The body schema—the brain's representation of the body—may become distorted, leading to feelings that the affected limb is swollen or foreign even when it appears normal. This explains why patients often describe their limb as feeling "different" or "wrong."

4. Musculoskeletal System Muscles in the affected limb undergo changes including atrophy (wasting) from disuse, spasm, and weakness. Joints may become stiff with reduced range of motion, potentially progressing to contractures if untreated. Osteoporosis (bone density loss) can occur in the affected bones due to altered sympathetic innervation and immobility—a process sometimes called Sudeck's atrophy. These changes contribute significantly to functional impairment and disability.

5. Integumentary System (Skin) The skin undergoes characteristic trophic changes in CRPS including thinning and becoming shiny, changes in hair growth patterns (either excessive or loss), nail changes (ridging, brittleness, slowed growth), and color changes due to altered blood flow. These trophic changes result from chronic autonomic dysfunction and are indicators of long-standing CRPS.

Physiological Mechanism

The primary mechanisms underlying CRPS Type I involve a complex interplay of inflammation, autonomic dysregulation, and central sensitization:

  1. Initial Injury Response: Following injury, there is an initial inflammatory response with release of cytokines and inflammatory mediators
  2. Autonomic Dysregulation: This triggers abnormal sympathetic nerve activity, causing disordered blood flow and sweating
  3. Peripheral Sensitization: Nociceptors become hyperactive and generate excessive pain signals
  4. Central Sensitization: The spinal cord and brain amplify pain signals, creating a self-sustaining pain cycle
  5. Trophic Changes: Long-term dysfunction leads to tissue changes including osteoporosis, muscle atrophy, and skin abnormalities

At the Cellular Level

At the cellular level, CRPS Type I involves activation of immune cells (mast cells, macrophages, T-cells) that release pro-inflammatory substances. These substances sensitize nociceptors and sympathetic neurons. Nitric oxide and other vasodilators cause abnormal blood flow changes. In the spinal cord, glial cells (astrocytes and microglia) become activated and contribute to central sensitization. These cellular changes create a self-perpetuating cycle of pain and dysfunction that becomes increasingly difficult to break over time.

Special Classifications

By Pattern of Spread:

  • Localized: Symptoms confined to the initially affected region
  • Contiguous Spread: Symptoms extend to areas adjacent to original site
  • Mirror-Image Spread: Symptoms develop in the opposite limb
  • Generalized: Symptoms affect multiple non-contiguous areas

Causes & Root Factors

Primary Causes with Mechanisms

1. Trauma and Injury (Most Common Trigger) The most common precipitating factor is trauma to the affected limb. This includes:

  • Fractures (particularly distal radius/wrist fractures and ankle fractures)
  • Sprains and strains
  • Surgical procedures (especially carpal tunnel release, mastectomy, joint replacement)
  • Crush injuries
  • Burns and scalds
  • Minor cuts, bruises, or insect bites

The key characteristic is that the pain and other symptoms are grossly disproportionate to the severity of the initial injury—this "disproportionality" is the hallmark feature that should raise suspicion for CRPS.

2. Medical Procedures Various medical interventions can trigger CRPS Type I including:

  • Surgical procedures (particularly orthopedic and hand surgeries)
  • Injections (including vaccination)
  • Cast application or rigid immobilization
  • Venipuncture or IV catheter placement
  • Even diagnostic procedures that are typically well-tolerated

3. Neurological Events

  • Stroke (cerebrovascular accident)
  • Heart attack (myocardial infarction)
  • Brain injury
  • Spinal cord injury These events can disrupt normal nervous system function and trigger the cascade leading to CRPS.

4. Infections Some cases of CRPS appear to be triggered by infections, either localized to the affected limb or systemic. The infection may have resolved but leaves behind dysfunction in the nervous system.

At Healers Clinic: Root Cause Analysis Approach

At Healers Clinic Dubai, we take a comprehensive approach to understanding why CRPS developed in each patient. Our integrative assessment includes:

  1. Trigger Identification: Detailed history of the precipitating event and timeline
  2. Constitutional Assessment: Evaluating overall health status, including homeopathic constitution
  3. Ayurvedic Evaluation: Assessing doshic imbalances that may contribute to susceptibility
  4. Nutritional Status: Checking for deficiencies that may impair healing (vitamin D, B vitamins, magnesium)
  5. Nervous System Assessment: Using NLS screening to evaluate autonomic function
  6. Inflammatory Markers: Comprehensive lab testing to identify underlying inflammation
  7. Stress and Lifestyle Factors: Evaluating psychological and environmental contributors

This comprehensive approach allows us to develop individualized treatment plans that address not just the symptoms but the underlying contributing factors.

Signs & Characteristics

Characteristic Features (Budapest Criteria Signs)

Primary Signs (Must Be Present):

  • Severe burning or throbbing pain in the affected limb
  • Allodynia (pain from light touch or temperature changes)
  • Hyperalgesia (exaggerated pain response to painful stimuli)
  • Edema (swelling) of the affected region
  • Changes in skin temperature (usually cooler, sometimes warmer)
  • Changes in skin color (red, purple, pale, or blotchy)

Pattern Recognition

Classic CRPS Presentation: Pain + swelling + color change + temperature change = classic CRPS presentation requiring urgent evaluation

Alternative Presentations:

  • Pain + weakness + atrophy = consider neuropathic cause
  • Pain + joint stiffness + contractures = late-stage CRPS or alternative diagnosis

Temporal Patterns

  • Onset: Usually within days to weeks of initial injury (can be immediate or delayed)
  • Pain Pattern: Continuous with intermittent exacerbations
  • Temporal Variation: Symptoms often worsen with stress, cold, or activity
  • Diurnal Patterns: Some patients report worse pain in morning or evening

Associated Symptoms

Co-Occurring Symptoms

Warning Combinations

Seek immediate care if you experience:

  • Sudden severe worsening of pain + fever = possible infection
  • Pain + swelling + chest pain = possible cardiac event
  • New weakness/numbness + CRPS history = possible neurological complication
  • Increasing difficulty breathing = rare but serious complication

Systemic Associations

CRPS primarily affects the local region but can have broader implications:

  • Mirror-Image CRPS: Some patients develop similar symptoms in the opposite limb
  • Spreading CRPS: Symptoms may spread to other areas of the body
  • Psychological Impact: Depression, anxiety, and post-traumatic stress are common
  • Sleep Disorders: Chronic pain disrupts sleep patterns nearly universally

Clinical Assessment

Key History Elements

1. Pain Characteristics

  • Location and radiation
  • Quality (burning, throbbing, stabbing, aching)
  • Severity (use validated scales like VAS or NRS)
  • Temporal pattern (constant vs. intermittent)
  • Exacerbating and relieving factors
  • Impact on sleep and daily activities

2. Precipitating Event

  • Nature of initial injury or event
  • Time between event and symptom onset
  • Severity of initial injury (and whether it seems disproportionate)
  • Treatment received for initial injury

3. Associated Symptoms

  • Swelling (onset, progression, location)
  • Temperature changes (which direction, constant or variable)
  • Color changes (red, purple, pale, blotchy)
  • Sweating abnormalities
  • Weakness or clumsiness
  • Tremor or spasms

4. Medical History

  • Previous injuries to the affected limb
  • History of other pain conditions
  • Medical conditions (diabetes, autoimmune diseases)
  • Current medications
  • Psychological history

Self-Assessment Questions

If you've experienced an injury, ask yourself:

  1. Is my pain much worse than I would expect from this injury?
  2. Is there swelling that seems excessive?
  3. Is one limb noticeably different in temperature from the other?
  4. Has the skin color changed in the injured area?
  5. Is the area extremely sensitive to touch?
  6. Are these symptoms getting worse instead of better with time?

If you answer "yes" to several of these questions, especially the first one, consider seeking evaluation for CRPS.

  • Infection: Acute onset, fever, elevated white blood cells

CRPS vs. Blood Clot (DVT):

  • CRPS: Pain out of proportion, color changes, temperature changes
  • DVT: Pain localized to calf, swelling, positive Homan's sign

CRPS vs. Neuropathy:

  • CRPS: Usually unilateral, autonomic features prominent
  • Neuropathy: Usually bilateral, symmetric, sensory predominant

Conventional Treatments

Medications

1. NSAIDs Non-steroidal anti-inflammatory drugs like ibuprofen, naproxen, and celecoxib can help reduce inflammation and provide pain relief. They are most effective in the acute phase. Long-term use requires monitoring for gastrointestinal, renal, and cardiovascular effects.

2. Corticosteroids Oral corticosteroids (prednisone) can be very effective in acute CRPS, reducing inflammation and modulating immune function. They are typically used for short courses due to side effects. Some protocols use intravenous methylprednisolone for severe cases.

3. Antidepressants Tricyclic antidepressants (amitriptyline, nortriptyline) and SNRIs (duloxetine, venlafaxine) can help manage neuropathic pain and improve sleep. They address both pain and associated depression and anxiety.

4. Anticonvulsants Gabapentin and pregabalin are first-line treatments for neuropathic pain in CRPS. They work by modulating calcium channels and reducing excitability of pain neurons.

5. Bisphosphonates Alendronate, pamidronate, and other bisphosphonates can reduce bone pain and halt osteoporosis in CRPS. They are particularly useful in chronic cases with significant bone involvement.

6. Topical Medications Capsaicin cream or lidocaine patches may provide localized pain relief with minimal systemic effects.

Procedures

1. Sympathetic Nerve Blocks

  • Stellate Ganglion Block: For upper extremity CRPS; injection in the neck blocks sympathetic nerves
  • Lumbar Sympathetic Block: For lower extremity CRPS; injection in the lower back These provide dramatic temporary relief and may help break the pain cycle.

2. Spinal Cord Stimulation For chronic, treatment-resistant cases, spinal cord stimulation may be considered.

3. Intrathecal Pump Delivers pain medication directly to the spinal cord for severe cases.

Pain Management Approaches

  • Physical Therapy: Graded motor imagery, desensitization, functional restoration
  • Occupational Therapy: Maintaining activities of daily living
  • Psychological Support: Cognitive behavioral therapy, coping strategies
  • Transcutaneous Electrical Nerve Stimulation (TENS): Temporary pain relief
  • Biofeedback: Temperature regulation and stress management

Self Care

Overview

While professional treatment is essential for CRPS Type I, self-care strategies can support recovery and improve quality of life.

Immediate Self-Care

  1. Elevation: Elevate the affected limb to reduce swelling; use pillows to keep above heart level when resting
  2. Protection: Gently protect from injury and extreme temperatures; avoid tight clothing
  3. Gentle Movement: Within pain limits, gently move to prevent stiffness; avoid complete immobilization
  4. Contrast Baths: If tolerated, alternating warm and cold water may improve circulation
  5. Stress Management: Practice relaxation techniques as stress exacerbates CRPS symptoms

Home Remedies

Anti-Inflammatory Nutrition:

  • Omega-3 fatty acids (fatty fish, walnuts, flaxseed)
  • Colorful fruits and vegetables (antioxidants)
  • Whole grains
  • Turmeric and ginger (anti-inflammatory spices)

To Avoid:

  • Processed foods
  • Excess sugar
  • Trans fats
  • Alcohol
  • Caffeine (in excess)

Lifestyle Modifications

  • Maintain appropriate activity levels without overexerting
  • Use pacing strategies to balance activity and rest
  • Practice good sleep hygiene
  • Avoid smoking completely
  • Limit alcohol
  • Maintain social connections and seek support

Home Management Protocols

  • Keep a pain diary to track symptoms and identify triggers
  • Document responses to treatments
  • Use prescribed medications as directed
  • Attend all follow-up appointments
  • Communicate openly with healthcare providers about symptom changes

Prevention

Overview

While not all cases of CRPS Type I can be prevented, certain strategies may reduce risk, especially after injury or surgery.

Primary Prevention

Following injury or surgery:

  • Early mobilization within pain limits (as directed by healthcare provider)
  • Adequate vitamin D and calcium for bone health
  • Proper immobilization techniques with adequate padding
  • Early and effective pain management
  • Patient education about warning signs for early intervention

Secondary Prevention

For patients who have developed CRPS:

  • Early intervention improves outcomes dramatically
  • Consistent treatment adherence prevents progression
  • Identifying and avoiding personal triggers reduces exacerbations
  • Regular exercise maintains function
  • Stress management reduces symptom flare-ups

Prevention Checklist

  • Adequate vitamin D levels (check with blood test)
  • Good physical conditioning before any scheduled surgery
  • Early mobilization after injury or surgery (within pain limits)
  • Effective pain control in acute phase
  • Awareness of warning signs
  • Prompt evaluation if symptoms seem disproportionate

When to Seek Help

Red Flag Signs (Seek Emergency Care)

  • Sudden severe worsening of pain
  • Signs of infection (fever, redness, warmth, pus)
  • New weakness or numbness
  • Chest pain or shortness of breath
  • Inability to move the affected limb
  • Severe headache or confusion

Additional Warnings

Seek prompt evaluation if:

  • Pain is much more severe than expected from injury
  • Swelling is getting worse instead of better
  • Temperature differences between limbs are increasing
  • Skin color changes are spreading or worsening
  • Allodynia (extreme touch sensitivity) is developing
  • Function is declining (less movement possible)

Prognosis

Expected Course

General Prognosis: Prognosis depends significantly on early intervention. Patients treated within 3-6 months of symptom onset often achieve significant improvement or complete resolution. After 12 months, chances of complete recovery diminish, and treatment focuses on symptom management and function optimization. Approximately 30-40% of patients experience persistent symptoms despite treatment.

Recovery Timeline

  • Early Treatment (0-6 months): Best outcomes; 70-80% may improve significantly
  • Delayed Treatment (6-12 months): Reduced but still meaningful improvement possible
  • Chronic CRPS (>12 months): Focus shifts to management and function optimization

Factors Affecting Outcome

  • Early Diagnosis/Treatment: Most important factor
  • Younger Age: Generally better prognosis
  • Upper Extremity: May have better outcomes than lower extremity
  • Psychological Factors: Affect coping and recovery
  • Social Support: Improves outcomes

Success Indicators

Positive signs indicating good prognosis:

  • Good response to initial treatments
  • Stable or improving symptoms
  • Maintained function in affected limb
  • Effective coping strategies
  • Strong support system

FAQ

General CRPS Questions

Q: What is the difference between CRPS Type I and Type II? A: CRPS Type I (formerly called Reflex Sympathetic Dystrophy) occurs without identifiable nerve injury, while Type II (causalgia) occurs after a documented nerve injury. Both have similar symptoms and treatment approaches. The distinction is important for prognosis but doesn't significantly change treatment.

Q: Can CRPS spread to other parts of my body? A: Approximately 30-40% of patients experience spreading of symptoms. This can occur through "mirror-image" spread (opposite limb) or contiguous spread (nearby areas). Spreading is more common in chronic, untreated cases.

Q: Is CRPS a psychological condition? A: No, CRPS is a real physical condition with identifiable physiological changes. However, psychological factors can influence pain perception and coping. The condition can lead to psychological symptoms like depression and anxiety.

Q: Will I need surgery for CRPS? A: Surgery is not typically indicated for CRPS itself. However, if CRPS develops after surgery, additional surgery may be contraindicated as it can worsen symptoms. Sympathetic nerve blocks are procedures (not surgery) that may be recommended.

Treatment Questions

Q: Can integrative treatments replace conventional medicine for CRPS? A: Integrative approaches complement conventional treatment but should not replace evidence-based care for CRPS. Working with both conventional and integrative providers ensures safe, comprehensive care.

Q: How long does CRPS last? A: Duration varies significantly. With early treatment (within 3-6 months), many patients recover within 1-2 years. Without treatment or with delayed treatment, CRPS can become chronic and persist for years or decades.

Q: Can CRPS be prevented after surgery or injury? A: Some measures may reduce risk: early mobilization, adequate vitamin D, appropriate pain management, and patient education. However, not all cases can be prevented.

Q: Is there a cure for CRPS? A: There is no single cure for CRPS, but many patients achieve significant improvement or complete resolution with comprehensive treatment. Early intervention offers the best chance for cure.

Myth vs. Fact

Myth: CRPS is all in your head Fact: CRPS has clear physiological changes including autonomic dysfunction, inflammatory processes, and measurable changes in the nervous system. While psychological factors can affect pain perception, the condition is absolutely real.

Myth: If the initial injury was minor, CRPS can't be serious Fact: CRPS is notorious for occurring after minor injuries—the pain and symptoms are disproportionate to the triggering event, which is precisely what makes it recognizable.

Myth: Once CRPS becomes chronic, treatment won't help Fact: While early treatment offers the best outcomes, many patients with chronic CRPS still achieve meaningful improvement with comprehensive treatment, though goals may shift toward management and function optimization.

Myth: amputation cures CRPS Fact: Amputation does not cure CRPS and may actually worsen it. The changes in the nervous system that drive CRPS remain regardless of whether the affected limb is present.
