Thanks all for the responses. Been seeing a PT for the last few weeks. She has been doing a lot of myofascial release in conjunction with a lot of stretching and exercise. I have already noticed a marked improvement in my posture. PT says my curve is now on the high end of average. She says my kyphosis is within the “normal” limits.
My back muscles were extremely tight. Took multiple sessions of “popping” the knots, but my back already feels different with a better cosmetic appearance.
