Expert Treatment for Severe Nerve Pain, Swelling & Sensory Changes

Complex Regional Pain Syndrome (CRPS), also known as Reflex Sympathetic Dystrophy (RSD), is a severe and often debilitating chronic pain condition that can affect many parts of the body — most commonly the arms and legs. The condition typically begins after trauma, injury, fracture, or surgery, but in some cases, it develops without a clear trigger. At iMsk & Spine Group, we understand how overwhelming CRPS can be, both physically and emotionally. Our team provides gentle, compassionate, and highly specialized care designed to reduce pain, restore function, and improve quality of life.

What Is CRPS (Complex Regional Pain Syndrome)?

CRPS is a disorder of the nervous system in which the body’s pain signals malfunction — sending intense pain in response to even mild or normal touch. It causes a combination of nerve, skin, blood vessel, bone, and muscle abnormalities, making early diagnosis and treatment essential.

CRPS is sometimes referred to as RSD (Reflex Sympathetic Dystrophy), an older term for forms of the condition where a definitive nerve injury may not be found.

Whether labeled CRPS or RSD, the condition requires thoughtful, comprehensive care and ongoing support.

Causes of CRPS/RSD

While CRPS most often develops after:

  • Fractures
  • Sprains or ligament tears
  • Surgery
  • Crush injuries
  • Burns
  • Infections

It can also occur:

  • After seemingly minor injuries
  • Without any identifiable cause

The exact mechanism is not fully understood, but experts believe it involves a combination of:

  • Nervous system malfunction
  • Abnormal inflammation
  • Changes in pain pathways
  • Vascular dysfunction (blood flow changes)

Symptoms of CRPS/RSD

CRPS can cause an unusual mix of sensory, skin, motor, and nerve symptoms, including:

Pain Symptoms

  • Severe burning or shooting pain
  • Extreme sensitivity to touch (allodynia)
  • Pain disproportionate to injury

Skin & Circulation Changes

  • Swelling
  • Changes in skin temperature (hot or cold)
  • Skin discoloration (red, purple, blue, or pale)
  • Shiny or thinning skin
  • Excessive or reduced sweating

Hair & Nail Changes

  • Faster or slowed hair growth
  • Brittle, thickened, or ridged nails

Motor Symptoms

  • Weakness
  • Tremors
  • Muscle spasms
  • Difficulty moving the affected limb
  • Contractures in advanced cases

Advanced Symptoms

  • Bone thinning (osteopenia)
  • Severe muscle atrophy
  • Debilitating pain with movement

CRPS is a condition where early evaluation and treatment greatly influence long-term outcomes.

The Three Stages of CRPS

CRPS may progress through stages, though not every patient experiences all three:

Stage 1: Acute Phase

  • Lasts weeks to months
  • Swelling
  • Warmth and redness
  • Burning pain
  • Sensitivity

Stage 2: Dystrophic Phase

  • Increased stiffness
  • Cooler skin temperature
  • Worsening pain
  • Hair and nail changes
  • Loss of mobility

Stage 3: Atrophic Phase

  • Significant mobility limitations
  • Contractures
  • Muscle atrophy
  • Joint stiffness
  • Severe functional impairment

Early intervention helps reduce progression through these stages.

How We Treat CRPS/RSD at iMsk & Spine Group

Because CRPS affects multiple systems in the body, treatment requires a comprehensive, multi-layered plan.

1. Pain Management

  • Nerve-calming medications
  • Anti-inflammatory treatments
  • Neuropathic pain therapies
  • Sympathetic nerve blocks
  • Advanced interventional pain procedures

2. Rehabilitation & Physical Therapy

  • Gentle desensitization techniques
  • Range-of-motion exercises
  • Graded motor imagery
  • Mirror therapy
  • Strength and flexibility restoration

3. Functional Improvement

  • Occupational therapy
  • Adaptive strategies to maintain independence
  • Support for mobility and daily tasks

4. Psychological & Emotional Support

Chronic pain can affect mental well-being. We provide resources and support to help patients manage stress, anxiety, and the emotional impact of CRPS.

5. Long-Term Monitoring

CRPS requires ongoing attention. We work closely with patients over time to adjust treatment as symptoms change and improve.

CRPS & RSD FAQ

Is CRPS curable?

While there is no single cure, early and comprehensive treatment can significantly reduce symptoms and improve quality of life. Many patients experience meaningful improvement.

How quickly does CRPS progress?

Progression varies greatly. Some patients have mild symptoms that stabilize, while others experience worsening stages. Early care offers the best outcomes.

Can CRPS spread to other parts of the body?

In some cases, symptoms can spread. Prompt treatment helps reduce this risk.

Why is CRPS so painful?

CRPS affects the nervous system’s pain-signaling pathways. The brain interprets even mild stimulation as intense pain due to nerve dysfunction.

How do you diagnose CRPS?

Diagnosis is based on clinical evaluation, symptom presentation, and ruling out other causes. Imaging and nerve tests may support diagnosis.

Can physical therapy help, or will it worsen symptoms?

Gentle, guided physical therapy is essential for recovery. While movement may be uncomfortable at first, targeted therapy prevents stiffness, improves function, and reduces long-term disability.
