I am new to this site but looking for someone who may be going through the same thing I am. I am having problems with my left arm, anything overhead or behind my back hurts, just fixing my hair is a struggle. It is very weak. I had an xray done wich was normal and done 12 rounds of physical therapy. My insurance denied my doctor's request for an MRI so they are re-submitting that. I am told that it is hard to tell if it is my rotator cuff or problems with a disc. I am very frustrated and want this taken care of. Has anyone else had problems like this and what was the outcome? Any advice or story would help.
