I’ve had issue with dents in the top of both of my butt cheeks for a while now. One side is deeper than the other and when I sit on a hard surface, I notice that my butt cheek folds where the indent is. I’m 141 lbs and around 5’3/5’4 and started working out again a few months ago. I’ve not had any trauma or injections to my butt cheeks so unsure what is causing this and what I can do to help without having surgery to smooth out dints and have a rounder shape?
