About six months ago, I had moderate pain running down my under arms to my elbows along the
nerve. Everytime I would stretch my
arm the
nerve would hurt. It first started on one
arm, then the other shortly after. The stinging pain lasted for several months. After a while, it diminished. Over the last few weeks it has returned. It is very uncomfortable. Now it is not only under my arms, it goes down my side and now my right forearm is starting to have the same problem. Any thoughts?
