CRPS Treatment: A Comprehensive Approach to Complex Regional Pain Syndrome
Complex regional pain syndrome (CRPS) is one of the most challenging and misunderstood conditions I treat. It's also one where early, aggressive intervention makes the biggest difference in long-term outcomes. Unfortunately, many patients with CRPS spend months or years cycling through ineffective treatments before reaching a specialist who can help.
What Is CRPS?
CRPS is a chronic pain condition characterized by:
- Disproportionate pain (far greater than the original injury would explain)
- Changes in skin color, temperature, and sweating in the affected limb
- Swelling and skin changes
- Movement abnormalities and allodynia (pain from touch that should not be painful)
- Spreading beyond the original injury site
It typically follows a trauma — often minor — to a limb, but can also occur after surgery, fracture, or nerve injury. CRPS Type I (no confirmed nerve injury) is more common; CRPS Type II follows confirmed nerve damage.
The Importance of Early Treatment
The neurobiological changes in CRPS can become self-reinforcing over time. Early intervention — in the first 6–12 months — produces significantly better outcomes than treatment begun years after onset. If you suspect CRPS, do not wait.
Evidence-Based Treatment Approaches
Sympathetic Nerve Blocks
Lumbar sympathetic blocks (for lower extremity CRPS) or stellate ganglion blocks (for upper extremity CRPS) interrupt the sympathetic nervous system contribution to CRPS pain. A series of blocks can break the pain cycle and improve dramatically.
Physical Therapy (Desensitization)
Graded motor imagery and mirror therapy help retrain the brain's representation of the affected limb. Physical therapy with a CRPS-experienced therapist is essential alongside interventional treatment.
Ketamine Infusion Therapy
CRPS has one of the strongest evidence bases for ketamine infusion among chronic pain conditions. Multiple studies demonstrate significant pain reduction in 70–80% of CRPS patients following infusion therapy.
Spinal Cord Stimulation
SCS is the most strongly evidence-supported invasive treatment for CRPS. Randomized controlled trials demonstrate that SCS provides superior and durable pain reduction compared to physical therapy alone for CRPS. I consider SCS for CRPS patients who have not achieved adequate relief from sympathetic blocks and ketamine.
Low Dose Naltrexone
LDN's anti-neuroinflammatory mechanism makes it a useful adjunctive treatment for CRPS, and I use it as part of multimodal management.
A Personal Note
CRPS is a condition where patients often feel dismissed, misunderstood, or told the pain is "in their head." It is not. CRPS is a real, biological condition with identifiable pathophysiology, and it has treatments that work. If you or someone you know has CRPS, call 516-492-3100 to schedule a consultation with a pain specialist who specializes in this condition.
