I have since this with a B12 deficiency and/or a Iron deficiency.
A simple lab could rule this out.
go online and take a quiz for candida which is bacterial overgrowth.
do not take any antibiotics, they make it worse.
see what other symptoms might be a match. If it is candida, you will have to dedicate yourself to a lot of lifestyle adjustments including NO sugar, alcohol, processed grains, sweet fruit, coffee, chocolate, and eat very very healthy. Plus ginger, garlic, avocado, coconut oil, oil of oregano, and some other herbal remedies.
It's no picnic but you won't get rid of it any other way and doctors will do nothing for you but cost money and frustration. Don't let them give u antibiotics, that is how the problems start for a lot of people.
Good luck.
