What does it mean if months after explant (behind the muscle ) & enbloc, it feels hard in the top front pectorial muscle and the side ofn he breast is numb?
"Enbloc" surgery is for cancer treatment only and not removal of implants. You may have some scar tissue in the area, or even retained fluid. An ultrasound exam might be helpful. I would suggest meeting with your plastic surgeon and discussing your concerns.
