I think that you should get a professional diagnoses to be sure you have scar tissue first. If you do, taking a good digestive enzyme product such as Omega-Zymes in plentiful amounts (3-4 capsules) on an empty stomach should help eventually because digestive enzymes break down fibrin, which is what scar tissues are made from. Adding the digestive enzyme serrapeptase should make the process even more effective.
To answer you original question, yes deep massage can help break up scar tissue but it could also further cause problems if there is something else wrong besides scar tissue.
