Look into the possible diagnosis of RSD relfex sympathetic dystrophy, lots of the symptoms you are discribing is what I deal with on a daily basis. Another name for it is CRPS complex regional pain syndrome. They consider it a neurological condition and there is a forum on here just for that, so if you write on that forum and give them your symptoms they maybe be able to help even more. Have you seen a pain specialist, that is who I saw that was able to help me. I went through 56 doctors of every specialty in 3 states and it was a pain managment doctor who was able to find the diagnosis. even if its not RSD a doctor that deals with pain might be able to help you.
