Some people put yogurt in the vagina instead of eating it, in order to get the acidophilus down where it’s needed more quickly. You can insert the yogurt directly into the vagina by dipping a tampon (the kind without an applicator, like the OB brand) into unsweetened yogurt and then inserting it into the vagina. Remove the tampon after an hour or so. Do not forget it’s there.
You can also freeze yogurt in the fingers of a sterile plastic glove, and then insert the frozen yogurt popsicle in the vagina like a tampon. This can be a bit messy, so you may want to use a sanitary pad for a few hours. Believe it or not, the icy yogurt will feel good against your inflamed vaginal walls.
