I've had three shoulder surgeries.....after the 1st one and after extensive rehab I was feeling good and throwing better than ever in the spring. As I started to let it go a little more and incorporate my curve again, I heard a pop and dropped to the ground. I was sure i had re-torn the rotator cuff. I was done. Over. Turned out, it was just scar tissue tearing away. Cortisone shot and 2 weeks rest and the pain was gone. Hope this is the case for AK....that first time coming back from surgery, you are certain that every pain or twinge is a re-injury. Fingers crossed.
