Hi
Welcome to the MedHelp forum!
Foul smelling and redness at umbilicus or navel or belly button could be due to fistula, boil, or infection. Umbilical fistulas are narrow tubes connecting the outer skin with anything inside like intestine, mesentry etc. Boils in the umbilicus can also burst and release blood and foul smelling pus. In rare cases it could be Meckel’s diverticulum. Do consult your doctor. Hope this helps. Do let me know if there is any thing else and keep me posted. Take care!
