I hate to hear it brother. About 3 yrs ago I tore my bicept muscle off the bone in a skiing accident.
I know this is not what you want to hear but, I have to be honest. Shoulder surgery is the worst pain I have ever dealt with. I had four holes punched in my shoulder. The Dr. had to grind my bones and drill a hole at the top of my shoulder, through the bone.
The part that really sux, about 3 or 4 months later you will think you are feeling better. Trust me, take it easy. I tried to work in the hay field and about fell out with pain. It took me about 9 months until I was close to 100%.
The good news is that today I feel better than ever. I had a bunch of bad tissue from playing football throughout High School and some College years. The Dr. said he removed a ton of tendonitis. Today my left shoulder feels much better than my right.
All in all....I would do it again. The rehab sux and the road is painful and frustrating. But I'm better today, and much stronger.
Good luck. Take the Pain Pills. And ask for the "take home" morphine pump.
