I think your massaging the scar and area was what the OT will do and more. I had a mastectomy and one lymph node removed in 11/21. Radiation followed in January and lymphedema soon after. I've been seeing the OT since then. Besides the breaking up of scar tissue and cording. I have been dealing with swelling in the breast area. I now exercise every day, wear a lymphedma pad at night and a camisole that compresses not only the breast but the abdomen as well. I feel that things are under control now. I hope to be finished with OT by the end of the year.
Good luck in your journey
