Hi hun sorry i’ve only just seen this!! I went form overs to unders because I didnt really like how they looked or felt- like balls in socks, I also wanted to go larger and felt that going under the muscle would support them more as they would be heavier, I think unders last longer too? I go to the gym quite a lot too and was starting to get rippling with my overs as i lost a bit of weight and going under has got rid of that. I definitely prefer my unders to my overs but I think its just personal choice! They just feel more securely held in place and don’t feel as heavy even though are heavier than my old ones! Im so sorry to hear you’re having problems!! I hope u manage to get it sorted!! overs really do look great its honestly just what ever you prefer, the second op they say you recover much quicker too so good luck!!! xxxx
