I am 5"1" and 128 pounds. I have always had a tiny waist and big boobs but my butt has never had much projection. Now it is even worse, no projection and just slides into the back of my leg. I also have some cellulite. Would an implant or fat injections be better? I have a flat belly but an extra roll in my lower back and flanks. If i need to travel outside of Atlantic Canada for the surgery, How long after surgery do I have to wait before I can fly 2 hours?
