Last week I had a UTI, but then I started feeling as if I had a yeast infection. Then the other day I discovered raw skin underneath the lips of my vagina and little red sores. The sores have gone away without crusting over, (as I've read if this were what I think and am praying that it's not), completely disappeared, but I still have one area with raw skin. Could this just be a reaction/infection to the amount and different kinds of medications I was on to treat the UTI and yeast infection?
