Hello My very nice neighbor gave me milk kefir that he made with live grains he bought online i drank it for 2 days. I then had anal and vaginal itching really bad. then it progressed to whole body itching with very small welts that would surface which caused me to scratch than disappearwhen i stopped scratching . the itching happenes more at night. I took benedryl that helps but im concerened as to the whole body itching ie: buttocks,scalp, feet,legs,arms,belly ,back but now no more anal or vaginal itching ??? could it be a yeast allergy
