I had a breast augmentation not even 6 months ago 375 mentor high profile over muscle. My biggest concern was loss of upper fullness after breastfeeding. My surgeon assured me that I would have the fullness I wanted but I don’t. I still have to wear a push up bra to get any cleavage. My left implant also feels like it moves all over the place. Could something be wrong? If I ask for a revision what would I need? Under the muscle?
