I can't give you advice on the surgery or recovery. I think you need to look at your life, what's important and what your future holds.
I was a good bencher, not world class but pretty damn good. My shoulder has been bothering me for about 8 months- some of you have heard my rant. Finally went to a good dr. One of about ten diagnoses is a SLAP tear. Bottom line- I'm 45 and need a complete shoulder replacement. I have 2 choices, quit powerlifting or keep at it and have to have surgery that much quicker. He said he'd like to fix the tear but there is nothing left to fix.
All I do is work and lift (an occasional whiskey drink). I'd give a lot to be able to have surgery and do what I love to do. But that's over.
I remember exactly when my shoulder started hurting. I asked how did I destroy my shoulder over such a short period of time. He said what probably happened was I had s SLAP tear playing football in high school and this is the result of 27 years of shoulder instability and heavy use. My shoulder, being as strong as it is the only reason why it was functioning the way it is supposed to.
My point, your shoulder is supposed to work a certain way. It's a complex joint and if not working correctly you accelerate damage. What's your activity level? You want to throw a ball with the grandkids?
