Complex Regional Pain Syndrome (CRPS)
Also called: RSD, causalgia
A limb pain condition where the nervous system's protection response misfires after an injury (often minor — a sprain, fracture, or surgery), producing pain wildly out of proportion with skin, temperature, and swelling changes. The single most important fact: early recognition and active movement-based treatment dramatically improve outcomes — this diagnosis punishes delay and immobilization.
Common signs
- Burning, severe pain in a limb exceeding the original injury's explanation
- Skin changes: color shifts (red/purple/mottled), temperature differences, unusual sweating
- Swelling and profound touch sensitivity (light touch feels like fire)
- Stiffness, tremor, or weakness; later, skin/nail/hair changes
- Guarding and fear of using the limb
Seek help now if
- This condition is its own urgency: pain + color/temperature/swelling changes after injury deserves evaluation within days, not months
- Signs of infection (fever, spreading redness) — different emergency
- Rapidly progressive weakness
If any of these is sudden or severe, call 911 or go to an emergency room. For the others, get examined before you start self-care.
What to do first
- Seek evaluation quickly if the pattern fits — the treatment window matters more here than almost anywhere in pain medicine
- Begin gentle, graded use of the limb immediately as guided — motion is medicine and disuse is fuel
- Start desensitization: progressive texture exposure retrains touch processing
The longer road
- The active model wins: graded motor imagery, mirror therapy, desensitization, progressive functional loading — a nervous-system retraining project with real evidence
- Multidisciplinary care is appropriate and often necessary — pain specialists, movement care, and nervous-system regulation working together
- Vitamin C after wrist fractures and similar injuries has evidence for prevention — worth knowing for next time
- Progress is nonlinear; measure by function gained monthly
Natural healing options we use
- Graded motor imagery and mirror-therapy programming
- Desensitization protocols and graded functional loading
- Gentle manual care as tolerated; PEMF
- Daily breathwork and nervous-system calming
- Omega-3s, magnesium, vitamin C/D support
About imaging
Primarily clinical; imaging excludes other causes and occasionally supports the picture.
Daily self-care
- Use the limb gently every day — protection through motion, not stillness
- Daily desensitization practice with textures
- Track function (what the limb DID), not just pain scores
