I m having burning and itching of the vagina, and an area on the inner vagina that appears to be a rash but no sores or lumps. I have whitish discharge that comes out in really tiny clumps however, it is not a lot and isn t noticeable unless i look at my genitals in the mirror . I recently treated for BV and yeast infection and i am currently on amoxicillin, and clarithromycin as well as lansoprazole for H pylori and I take doxycycline for acne, also last month was treated for chlamydia with arzithromycin. Could all these antibiotics be contributing to this discomfort? Or does this sound more like an STD, or yeast infection or BV?
