Like I said; I set myself back at least a month, endured a lot of pain and had to have cortisone shots to continue rehab after pushing it too hard.
Everyone I know who has had shoulder surgery has strained their shoulder at some point during rehab and were sure they were badly injured to the extent of having more surgery. I did, it was sure a sinking feeling to think you had to go back to square one. In all cases we got over our carelessness but had we listened to the Dr none of it would have happened in the first place.
A funny thing about having my collar bone ground off; I went into the bathroom to get a drink of water about 3am, I picked up the dixie cup full of water and aimed it at my mouth and hit the bottom of my chin, repeatedly. Reconfiguring my arm, shoulder, collarbone and some nerve damage made my aim off, it took me a week or so of retraining myself to hit my mouth with a cup in the dark. I didn't have a problem if I could see the cup and direct it.
