A question - I'm 8 weeks post-op from AVR (mechanical valve). My left side of the breast (closest to the incision) is still a bit numb. I'm also having some pain in the left breast. I've been to my PCP and he said they might have cut a nerve during surgery. Has anyone else had this? I go to my cardio at the end of this month and will ask him as well. I go back to work tomorrow and a bit nervous about having these pains when at work.
