I had rotator cuff surgery in 1997, after going for 17 years with an improper diagnosis. They kept on telling me I had tendonitis, and bursitis, which I did, but I had a torn cuff, impingement, bone spurs, and acromion was fucked up. I had at least 15 cortisone injection through the years. They also took out a few inches off the end of my acromion
I had the surgery in 97, and it took a full year to get back to 100% function. I had already built it back up in the 80s long before the surgery, and was a competitive AAU power lifter at 148lbs from 83-87, and also did non competition bodybuilding all through the 80s. I was competing in Marathon Running, and have a best time of 2 hours, 38 minutes, and change in the early 80s. I also lifted alot of weights.
All the time I was powerlifting ect, I had pain, and when I moved my arm a certain way, you could hear my shoulder crack across the room.
My surgery wasnt arthroscopic either Ive got a 6 inch scar where they opened me up. It was terrible pain, and I had to sleep in a recliner for at least a month. No way could a lay back on a bed. I tried, and trying to sit up, was like getting shot in the shoulder. I couldnt roll out of bed either. Same pain.. I also took no pain medication. They gave it to me, but I didnt take it. It took 1 full year to get back to where I could torture my shoulder again with weights, and now 25 years later, my shoulder is still as good as new. No restrictions, though I still do many of the PT exercises for warmups prior to lifting weights. Especially Bench Press, and Shoulders. I warm up on Bench with Dumbells.
The big thing about making a full recovery is to use alot of ice, especially after you do your exercises, and dont ever let up on your PT exercises. And you cant rush things. Bbe happy with small improvements. I used ice no less than 4x a day, 20 minutes at a time. I used a bag of frozen mixed veggies many times, right on the skin so it would numb the area. I would also get a styrofoam cup fill it full of water, freeze it, and do a massage on the injured area, peeling away the cup as the ice melts.
