About a year ago my right breast started to droop in an unnatural way (nipple down first), as compared to the right. I am also experiencing a fold at the bottom and the size of my right breast is now smaller than my left. Neither breast feels extra firm and I am experiencing zero pain; both breasts feel the same as always. My implants are under the muscle and around 12 years old. I was thinking capsular contracture but they aren't feeling extra firm.
