I've had shoulder problems since the very beginning of tri training. I did see an ortho who took x-rays and said I have a type II acromioin. I'd love to know some stretches to help my flexibility.
I get a very bad shoulder pain (left side only) when on the bike for over 45 minutes. The pain seems to be between my shoulder blades but only on the left side.
Often I also see an imbalance in the front muscles of the shoulder, such as the pectoralis, and the back muscles, such as the rotator cuff and shoulder blade stabilizers. I would recommend:
Differentiating between the different causes of rotator cuff-related pain is not important initially, because primary treatment for all of them is the same.
