Summary
This study tests whether a very low dose of naltrexone, a drug usually used for addiction, can reduce pain and other symptoms in people with Complex Regional Pain Syndrome (CRPS). Forty adults with CRPS will receive either the drug or a placebo for six months. The main goal is to see if the study is practical to run, but researchers will also track pain scores and side effects.
