I am thinking it is likely yeast. I have difficulty with chronic yeast infections and have learned to notice the slightest "feel" of my vagina. I learned many years ago that as soon as I notice my vagina that it is already beginning. I purchase a yeast cream on Amazon where I find it cheapest. Only one of the creams does not cause me to burn. Taro Clotrimazole 7 Vaginal Cream 45 g ( Pack of 3)
Brand: GYNE-LOTRIMIN 7 DAY at Amazon is under $20 for 3 tubes. it costs that much for one tube at the drug store.
