I noticed three days ago that I had a brown crust inside of my belly button and that there was a foul odor coming from it. I figured that this was due to a sweat buildup and made sure I cleaned my belly button thoroughly in the shower, and the problem seemed to be resolved. I exercise a lot and think that there might be a bacterial/fungal infection inside of my belly button that originated from the sweat, since I didn't have any cuts or scrapes in the area. The day after, however, the inside of my belly button looked red and irritated and seemed to be oozing. It almost looked like there was a red ring inside. I read that fungal infections in belly buttons happen, so I got some anti-fungal cream. This seems to be working somewhat, but I don't think the issue has gone away completely. I was thinking about going to an urgent care clinic, since my doctor isn't available on the clinic, but would prefer to see my regular doctor on Monday. Would that be too long to wait?
