question: About 7 weeks ago I had my gallbladder removed laparoscopically and an umbilical hernia repair. Although all was normal with my belly button (which is once again an "innie" since the hernia repair, I have a swollen lump inside my belly button. It does not hurt and feels kind of soft. I was treated a few weeks ago with antibiotics for an infection from the surgery. Could this new lump be another infection? What is it?
