I had my child 5 years ago. I have been working out and I am at my goal weight/pre-baby weight (when I was happy with my body). My stomach seems flat except for a small bulge/shelf just above my c-section scar. I am very unhappy with it. How can I get rid of it? I am somewhat hesitant of having surgery and don't want a big scar. (The scar along my ribcage is unrelated).
