I thought it was a
yeast infection or something, since people said you can get those
in your navel, but I have never had a yeast infection *anywhere*, so wasn't sure.
Usually, when I find that it has been "leaking" I swab it out with water, then with hydrogen peroxide. The peroxide always bubbles and fizzes, and recently, I have been experiencing sharp pain inside my belly button and a burning, itching sensation that last for some time after using the peroxide.
