I had Gyno surgery in 2011 when I was 15 or 16. I am now 27 and I feel like my chest still looks weird under the nipple. I am overweight right now, but working out with a trainer. It is hard to activate my chest when weight lifting or benching. Also there feels like my chest is sunken in under the nipple. Will my chest look better as I do more chest weights and lose fat or does it need to be corrected through surgery?
