Would this be fixable in the room or do I need another operation? How can I submit photos?
It's hard to answer this w/o an in person consult. Having said that, is the issue on the mastectomy side ? Were both breasts removed and reconstructed ? 6 months is not all that long depending on what was done. My suggestion is to return to your surgeon for an in depth conversation.
It could be capsular contracture, or scar tissue around the implant. You would likely need a corrective surgery in the operating room- but consult with your surgeon for a more detailed exam.
