i had my tubs tide the same way you did. what i have found out that is grown candida, high yeast. what i have tried is probio 5 from plexus slim and it works great. what i did before is soak a q-tip in alcohol that works .
Your case sounds just like mine, and from my experience is that it is my (GERD) gastroesophageal reflux disease. Seams that every time I don't take any medication for a couple of days it flairs up. I've had it so bad, it would start to come out of all my orifices. I would then get back on the acid blockers and ta-da, it's gone. I have gone to numerous doctors and none of them can tell my what is. Mine own doctors for 30 years said that he had never heard of such a thing. Never the less, I'm already in my fifty's and that seams to be the only thing that causes it for me. And just in case you don't believe that GERD could cause such a thing, check out this web site. Good luck ladies, Mustang Sally :)

I too have a sore red BB and I clean it with apple vinegar - I know it sounds weird but it works. Apple vinegar is a healer for so many things! Hope this helps.
I've had a smelly belly button off and on now for years ,as it is very deep and yes it does smell horrible . i will tell u something funny though well i thinks funny ..... i way laying beside my husband in bed and i hadnt had the smelly belly for a while ......i got a wif of a bad smell ,i started smelling the sheets as we sleep naked , i then blamed my husband for not wiping him bottom properly as thats what it smelt like .... after a argument i realised it was me my belly was the culprit , i never did tell him that how embarrassing , but now i know when i get that wif , its me hope u see the funny side too..
I too have a weight problem, so my belly button doesn't get much air, so it gets sore and red. My doctor gave me a cream called Bactroban. It is a fungus that grows because air does not get in there, and sweat sits in there. Whenever getting out of the shower, make a point to try out your belly button and put a little baby power in there to help with the moisture. Hope this helps!
I've had the same problem since I was a child, I'm now 53 years old. I can't remember if I read this or saw it somewhere on tv, but they said some people's umbilical cords never heal properly. However when I was child I was told to clean it daily alcohol and a qtip.
