Has anyone suffered from Bursitis in here? I just got it and have been out of training for a week. Im going out of my mind it sucks so bad not being able to do anything. I lift heavy pretty much year round and I think I developed Bursitis as well as hitting a heavy bag from this. My shoulder hurts pretty **** badly. Einstein is helping me trouble shoot through this, but i was wondering how many others ever had bursitis in thier shoulder.
