Softball is fun but not worth it, it only takes one throw to damage it so bad that not even surgery could not fix it. My brother had surgery last year on his rotator cuff, and is doing well but still not 100%. The worst part for him is that he can no longer play softball. Get it fixed now, rehab it and you never know, maybe in a year or so you could at least get out there and be the extra hitter, and if things are doing well then you can get back on 1st base.
