Complex Regional Pain Syndrome (CRPS)
CRPS is a rare chronic pain disorder that typically affects an arm or a leg which develops after an injury or surgery.
Clinical features include throbbing pain, hypersensitivity, swollen limb, discoloration, and change in skin and nails. Muscle spasms and joint stiffness are also not uncommon.
Early aggressive treatment may prevent chronic, disabling pain. Bisphosphonates and short courses of oral corticosteroids may improve pain. Vitamin C may reduce the risk of CRPS after a fracture. Medications like NSAIDs (like ibuprofen) anticonvulsants (gabapentin and pregabalin), antidepressants, and opioids have limited evidence for CRPS treatment.
