I believe I have bicep tenditis. Whenever I throw the ball hard or whenever I pitch my lower bicep and upper forearm start hurting a lot. It gets to the point where I can’t throw more than 30 pitches without severe pain and it is not getting any better.
I’ve read online it could be a couple things:
-weak cuff/scap stabilizers muscles
-weak and imbalanced tricep
I don’t think it can be improper warmup because I warm up well and stretch before I throw. And I thought it was bad mechanics,but I spent the last two months experimenting different ideas. I’m getting my arm up in time and I’ll be honest my mechanics are pretty good. I’m betting it has to be the 3rd or 4th option. But which one is it? Where do I go from here?
