<bot>: Hi. This is called an umbilical granuloma. IT has the classical characters of sticking smell and discharge as you explained. Since it has got a stinking discharge this can be an umbilical sinus or a fistula, wherein there is connection between the umbilicus and either the Uranus meaning the urinary bladder or the intestines with Nickels Diverticulitis.  I would suggest you first to get a clinical examination done by a Surgeon and CT scan of the abdomen to confirm the diagnosis with associated problems as discussed. You will an exploratory surgery and to deal with the findings.
