I have been waking up w/ severe arm pain that starts about half way between my arm pit and elbow and it just runs all the way down and usually my fingers and hand are just burning like crazy. This morning it was the worst it had been and now I am starting to lose more not strength but I am just not able to hold anything at all with it and right now me just typing it is falling a sleep please help me if any one knows anything about this and if I should go to the ER or what I am limited I don't have ins but I am left handed and this is the arm the is getting attacked.
