I always have this pain in my left arm, which only in my arms in the foreground. If the press is in the upper arm near the shoulder pain. I can not lift my arm at all, because it is too painful. It started about 4 weeks a little easier when it pretty embarrassed again. Has anyone suggestions what could be. I have hurt in any way, just see the pain of a day.
