@robinw All surgery causes scar tissue. You may be interested in this discussion about Myofascial Release which is a specialized form of physical therapy created by John Barnes. It can treat and loosen surgical scar tissue. Unfortunately, not all doctors are familiar with it, and often they don't thinks about the properties of living fascia and adhesions in it because in med school they study cadavers instead of living tissue.
