Yea, same here, following the studies had helped me fix a 18 year old shoulder tendon issue.

I owe that research group a lot.

What happened to you? Might anything you have learned help me? Recommended reading?

I too have a shoulder tendon issue: 14 months ago a loud one-time "pop" occurred while doing a simple external rotation shoulder exercise with very light weight. I immediately lost most strength lhs and the shoulder felt very loose. More than a year later + 1 steroid shot my shoulder is much better but still loose.

It's complicated, rotator cuff tear combined with a bunch of rib, shoulder and neck injuries. I never properly healed them, just rest, career in tennis ended after trying to rest and heal 3 times over 8 years.

YouTube and Physical Therapy combined with the UC David protocol has brought back more strength and mobility than I've ever had.

My main issue I had before was I kept pushing my injury too hard without proper remodeling.

The UC Davis protocol requires a specific isometric, loaded stretch while dosing Vitamin C and Type 2 Collagen an hour before isometrics.

It took about 6 months before I felt it getting significantly better, and I'm not fully healed yet, but I can actually throw balls to my kids without feeling my injury now.

Thank you! I searched for "UC Davis protocol for shoulder" and found Dr. Keith Baars at UC Davis and his research on tendons:

and "dastratman" has produced an excellent summary of Baars' and Ferriss' discussions:

I searched your old HN posts and found that you've explained this before to HN denizens! Thank you, thank you so much!

FWIW I've never been able to throw w/o shoulder pain and, now that you mention it, I may make it my goal to build up to that!
