5 days ago, (16 days Tummy Tuck post-op) I noticed a bump between my breastbones. I think it's a suture. I called my doctor and he said not to worry about it. It doesn't hurt, it's not swollen nor red. It's just a bump right below the skin. Do I need to have it looked at? I still can't wear pants or anything around my stomach. I can't even touch my stomach because it's so tight. What can I do?
