The symptoms you are discribing sounds alot like what I have I was diagnosed with RSD or Reflex Sympathetic Dystrophy. I am not sure if thats what you have but all those symptoms go along with RSD. RSD is caused by some kind of nerve damage, most times from some kind of injury while other times there is no none cause for the damage. I would try seeing a pain specialist. My condition is now full body as it wasnt caught soon enough, I went to every specialist and was so surprised that it took a pain specialist to diagnose it, some neurologist know about RSD but very few. I do hope this int what it is but just look into it and see how many of the symptoms you have. There is a forum on this site just for RSD or the new name CRPS Complex Regional Pain Syndrome. I do hope you find a diagnosis so you can get relief.
