Hi guys. I pitched throughout middleschool and highschool and i am now 26. I have gotten back into baseball and am now pitching for a senior team. However, I am having issues with shoulder impingement. The inside (pretty much the soft spot between your peck and your shoulder) gets pretty inflamed. I never had a solid arm slot when I was a kid. I pitched side-arm, complete overhand, and 3/4. Now that I am older and getting back into things, I am not sure what style would be the “least” likely to cause any more impingement. I attached a very short video of a sample throw. Right now I am favoring as i guess i call it “complete overhand”. Is this style bad for your shoulder? Could this be what possibly caused my issue in the first place?
Anyways, I am currently following a stretching program and not going too crazy at the moment. Any advice would be appreciated. Thank you guys!
