Low dose naltrexone for complex regional pain syndrome
Treatments studied
Part of Brain & nervous system, Pain clinical trials.
This trial tests whether a low dose of naltrexone, a medication that may help calm overactive immune and pain signals, can reduce pain and improve daily life in people with complex regional pain syndrome (CRPS), a chronic condition that often causes severe pain and swelling.
Summary written for real people, not researchers, by Clin2.
