How to release the skin attached to my muscles after gynecomastia surgery? (photo)

I don't know the exact procedure through which the doctor attached my skin to the muscle around the nipple. What exactly is the procedure? Secondly, is this process reversible? Will it involve scarring? I either want my skin to be attached entirely to the muscle like this one or be detached altogether now. This little attachment is not helping. I cannot bear the pain of the shearing stress when I move my chest against objects.
