Thank you all for your kind replies. So I'm not the only one experiencing this.......?
I am not on any meds, so no suspicions of meds inter-reacting....
Allergies...hm.. That gives me an idea: When I eat apple, avacado, pineapple, kiwi, stawberry, mango, banana, or carrot, celery, string beans..... well, just about any fruit or veggie... I immediately have itching in my mouth, throat, ears. Which is why I'm basically deprived of all these healthy foods.
So I'm thinking....the itching (creepy-crawly feeling) down there may be the same allergic reaction, only it's happening further down in the digestive tract. Actually, the other end of the tract.
Anyone else has had this reaction in their mouth? And has any intervention helped? Other than the obvious intervention: just omitting it from the diet....
