I had bilateral breasts reconstruction done with expanders and shapped silicone implants under pectoral muscles about 4 months ago. My right breast has a small indentation, hole on the upper pole near sternum. Also when I overuse pectoral muscle, arm, mainly the right breast because I'm right handed I have some pain in that area where the indentation is. What is this? Why do I have some pain? Can fat grafting help with indentation/small hole? Is it safe for bc patients to have fat grafting to the chest/breast area? Is it a safe procedure in general? any risks? Does it last? I know, many questions. Thank you for being so kind to reply them.
