Over 10 yrs ago I dealt with shoulder issues and know it's from doing pulleys at the gym. Some how I found a Sports Medicine Doctor and he does Prolotherapy. I had no dx, but have issues and he did 8 injections of Prolotherapy in the shoulder and I got 3 yrs of great relief. Prolo has taken off and the advances are PRP and are more costly. If people can get to Prolotherapy or PRP, this work can keep one from surgery which has no guarantees, and once done, can't be reversed.
