I had a bilateral mastectomy about three years ago. I could not have reconstructive surgery as I had radiation 10 years ago and my breast did not heal with the expander in it. My question is, I have been working out and it has made my scar feel like it has three sutures in it (at the beginning, middle and end, under my arm). It is beginning to be very uncomfortable. Should I go back to my surgeon. Is there a test I can have to see if there is anything there?
