Ahh some shit I can talk about. I won't bore you with the story of how it happened other than mine happened with DB's also... 3 years ago.... I'll just stick to the relevant stuff.
After living with this issue for 3 years I finally saw an Ortho last January. Blew off his advice and three months later I had no choice but to do the surgery. Went in for a torn Labrum because that's all the MRI showed. When I woke from surgery ( May 12th) I was told that in addition to the Labrum I has a torn rotator and a 1/2 torn biceps tendon. After fixing all of that I started Physical Therapy. 13 weeks later I was able to do push ups on the edge of a counter and curl 15# dumbells. I graduated their PT class a week early because I was ahead of the curve.
First bench work out was a month after that, end of August, first of Sep if my memory is correct. I got FUCKING OWNED with 65#... MAJOR hit to the ego since the Sunday before my surgery I had benched 315 for 3 sets of 8. Last Wednesday I worked up to 265 for 3. It's getting better and better but still hurts. Shit still gets little pangs in it from time to time. For example, this morning I grabbed the milk to may my kid some cereal, left shoulder had a sharp pain shoot down my arm and then was ok.
I'd like to say it's a quick recovery but it's not. Just commit to easing back into things if you get surgery and if you live with it know that it will get progressively worse. Stuff doesn't heal itself no matter how much ice and blue heat you put on it. Not to drag you down but you have to take care of yourself.
In the big picture of life, 8 months to a year in my case is nothing. Better take it easy to heal vs fuck shit up and be a guy who USED TO LIFT right?
Good luck man.
