I had a biopsy done a few years ago and the incision was made in my left nipple. Since then, I've had a lot of pain that I think is from that...possibly scar tissue, but my doctor says that's not possible and just chocks it up to be pain that I will have to deal with. I never had any problems until after the biopsy. The doctor has checked it and said he didn't feel anything and my mamogram doesn't reflect anything either. It's becoming more and more painful and I don't know what to do. HELP!!!!
