Within the last few weeks I have developed a tight, ripping feeling from under my left breast that extends over my ribs to my abdomen.After it intensified I checked the mirror and was shocked to be able to see 2lines pulling tightly.I went back to the surgeon and he said it was probably just nerves regenerating and normal and that I need to continue to massage(which I've done faithfully)and start stretching(I already do).Until now, I have had virtually no pain after surgery. Is this normal?
