I wasn't sure where to put this, but since my belly button is near my stomach, I thought it would be good to put this here.
For the last several years (I have no idea when this started, I just began noticing it), I have had yellow, crusty discharge coming from my belly button. It is not continuous, but rather comes and goes every week or so. I am a very clean person and bathe/shower regularly, and I am not very overweight (5"4' at 130lbs), so I don't believe it is lint or dried sweat or anything, It smells very bad, and is sometimes so strong that I can smell it through my shirt. 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. Usually the skin inside and around it turns red as well.
Does this sound like something serious? Should I go see a doctor about this? It's really starting to bother me, since I never know when it's coming and especially now since it hurts. :-( Thank you for all your help!
