My belly button smells like fishy sometimes also it hurts to its left and right should i be worried and sometimes i feel a stinging pin in it, my belly button looks normal tho shoudl i be worried?

I presume you insert finger into your navel to scratch it, and then smell a fishy odor. Odd smells and stinging pain may be from skin infections, fistula (tiny passageways from the skin to something inside), food that you eat, or from other places, such as the vagina. Anaerobic germs sometimes elicit fishy and other bad smells; determining whether normal or not requires a visit to a doctor!
