A torn muscle? Really? I mean, and because it wasn't the tendon they aren't doing anything for you??? Criminy!

Well, I don't know for sure, but I have had a torn tendon and that took years of work and exercise and injections to help me get back.. and sometimes I think it's still a problem (but that side was the main impact side for my accident so who knows?)

You need professional help like a physical therapist! They will determine whether you still need to rest it or if you should begin therapy with/for it... and what and how much.

Please take care of yourself. If you ignore it, you might lose use of the arm .. from what I hear... (((hugs)))
