There is no definitive diagnostic test to confirm crps. It is diagnosed by inproportionate pain levels compared to the initial injury, if there was one. Also it is diagnosed by elimination of other diseases that match the symptoms till all options are eliminated. It is a hard diagnosis to get to and many still suffer with crps but have been misdiagnosed as it is a very complex disease, hence the name complex regional pain syndrome. The best thing to do to get to a diagnosis is be persistent in your care and in the search for answers, even if you end up seeing several doctors. If you think you may have crps, look for a doctor that specializes in crps.
