Arm & Hand

Complex Regional Pain Syndrome

Severe, disproportionate limb pain with skin and temperature changes, often after injury.

Understanding it

CRPS is a malfunction of the pain and autonomic nervous systems, usually in an arm or leg after injury or surgery. Early, aggressive treatment matters — sympathetic nerve blocks, graded physical therapy, and neuromodulation offer the best outcomes when started promptly. Dr. Iyer treats CRPS with the urgency it deserves.

When to seek care

If limb pain after an injury seems far worse than it should be, or the limb changes color or temperature, seek evaluation quickly — early treatment changes the trajectory.
