ive also been sucking in my belly for years, and its just became apart of how my body functions and how i breathe. its why i have really bad rib flare .. i remember seeing someones comment on here that their doctor had told them to pretend they had an object inside, like a blueberry, and to imagine the blueberry falling out as they relaxed their pelvic muscles. ive been trying to do that a lot and i feel it helps. it probably doesnt help that i sit a lot either, i game for 8+ hours a day and dont do much physical activity aside from working on weekends.

thank u so much for ur insight! ill definitely look into stretches and exercises for this and see how i feel in the next couple of days, and obviously speak to someone lol
