I had a tummy tuck with mesh to repair my large diastasis recti. I have noticed that my upper abdomen bulges out a bit more than the rest. It is firm when I touch it as is my whole midline to my abdomen, but I can feel a hard bulge. Is this scar tissue or inflammation still? Above the bulge by my sternum is an indentation that I can push my finger into, is this diastasis that should have been sewn and is still open? How far up do surgeons sew? Do I need a revision?
