Welcome to the site....
Does your belly button leak puss which would be a sign of an infection? If it were an infection, I'd guess you would have it treated a long time ago.
An umbilical hernia is a possible cause.... I had one of those right above the belly button.
Anyway - have your URO take a look next time you are there.
