Causalgia is another term for which condition?

• A. Complex regional pain syndrome type II (CRPS II)
• B. Complex regional pain syndrome type I (CRPS I)
• C. Peripheral neuropathy without CRPS
• D. Repetitive strain injury

Answer: (A)

Causalgia refers to complex regional pain syndrome with a known nerve injury, which is now called complex regional pain syndrome type II. This distinguishes it from CRPS type I, where no definite nerve lesion is identified. In CRPS II the pain follows a specific peripheral nerve distribution and is accompanied by autonomic and inflammatory changes, which is the key feature linking causalgia to CRPS II. The other options describe conditions that either lack a nerve injury (CRPS I), are a broader peripheral neuropathy not meeting CRPS criteria, or are separate overuse injuries (repetitive strain injury).
