I would like to find out what could be wrong with my arm? Symptoms: pain and numbness from my armpit to the tips of my fingers. My hand feels like I am literally sticking my finger in a light socket and it is being electricuted. My fingers are cold to touch but feel like they are actually on fire burning really bad. I try to move my arm around thinking bad circulation but doesn't affect it at all. Could you please tell me what it could be? The strangest thing is that it is happening to my right arm, not my left.
