I have First Assisted on hundreds of umbilical hernia repairs, with and without mesh. It certainly sounds like a infection to me. I would tell my Doc "humor me" and put me on antibiotics! What's it going to hurt? Best wishes! jd1963
When my mom had hernia surgery that would require mesh, the surgeon said it was normal to have a fluid accumulation during healing. He said the fluid would be drained at the appropriate time, and it did not mean there was an infection at all. Just routine follow-up because the mesh causes a backup of fluid. Is that the problem?
