My belly button stung and smelled terrible. I used a cotton ball and soap and cleaned it out. There is still a bit of oder and it still hurts. I am a bit over weight, so I don't need people pointing that out. I am not a disgusting person, I take showers regularly and keep myself clean. I have PE class first thing in the morning so maybe its from sweating? Please help me understand whats going on. I'm already insecure and this doesn't help. Thanks.
