Food allergies can cause you to react in many places...and that area is one of them, just few ppl talk about it. Some ppl who are allergice to spicy food also experience burning or itching there.

Try going totally off sugars for 3 months. TOTALLY. Then slowly begin to add them back in, maybe only one item first ... some allergies are corrected by the body once they are allowed to rest fighting them (thus the 3 months)... others aren't.

If you have an allergy to sugars, and the 3 month provocative testing doesn't work... then you could go to an allergist for desensitization. It's not just about this itching, imo, because with sugars, your whole system can be upset, and have bigger problems later on. A real allergist won't laugh or say it's in your head..they KNOW what allergies do to ppl. TC!
