I have had three surgeries on my left shoulder.
First was a "clean up", no PT required, did the PT at home on my own.
Second and third were Rotator cusp repairs, etc. Had to sleep in a recliner for a month or so after surgery, arm in a sling for a while. Total recovery took a year, and was half way normal after 6 months. I did not take many pain killers, but had pain at night.
I would offer this advise, try and find what surgeon does the local college football surgeries on shoulders....you will have one heck of a surgeon if you do. Second, find what PT that particular surgeon likes, and many hospitals demand their PT people attend surgeries in a teaching hospitals.
After my third surgery, it feels like the pieces parts in my shoulder are not connected, but I hvae full use and not quite as strong. Lifting 50 lbs, repeatedly, can give me mild pain that I take 550mg of Neproxin for. So, I baby my shoulders, can reload and shoot without issues, use muzzle breaks on everything.
I hope anyone considering this surgery will take my advise to heart on finding the right doctor. Most people go for what ever is close, really bad decision. Find a surgeon that works on athletes, they are the best along with the PT that the surgeon has hands on experience with. My second surgery was a goat roping from the surgery to the PT.
