Yeah, motivation was never an issue with me so overtraining was a serious problem over the years. I was still training hard 4-5 days a week into my 40's but I have been forced to cut right back and act like a middle aged man (for once LOL)
I just went and saw a surgeon who looked at the MRI of my right shoulder and her first words were "Ooh wow... I bet that was fun" End result, she said there were a lot of surgeons that would give it a shot... but it probably wouldn't help and that she has more patients than she can see already and won't waste either of our time and money. Go do PRP instead... I appreciated that.
The guy in the video I linked seems to have the exact same symptoms that I have and three and a half weeks after treatment, he said he felt at least 85% better so that's super encouraging.
