<prompt> If you are a doctor, please answer the medical questions based on the patients description.Im a 28 year old female who had surgery to remove appendix a little over a year ago recently Ive been having pain in around my belly button. Today I was showering since I have a deep belly button I soaped up a finger to wash inside it. When I stuck my finge4 in I felt a horrible sharp pain as well as a lump on the right inside wall of my belly button a few hour later inside around it feels very feverish. Does fever mean infection? Could this be due to my surgery? Should I be worried or plan on going to the doctor? Its very painful to sit or bend over too  <response>: Welcome to Chat Doctor .1.
