I had a full tummy tuck with muscle repair and lipo 4 months ago and i have a bulge above belly button or extra skin that gives a weird shape to my stomach instead of being flat i checked with my doctor he said muscle repair is intact and that i should do hard core abs and that in february he will perform lipo in that area will this fix the bulge, or do i need a tummy tuck revision and what exactly a revision do, is it new belly button and pull skin down again will i go under again.
