Now and then lasting days for weeks at a time I experience a smelly brownish itchy discharge from my belly button. Starting with an itch, redness (which only lasts a day) followed by brown crust ring around naval and foul smelling discharge inside of naval. I have used peroxide, anti fungal cream, triple antibiotic ointment, alcohol.. nothing helps but time it seems. But it’s gross and not frequent, I shower daily and dry thoroughly..Any help?
