If you have been diagnosed as having a vaginal infection, and you have symptoms of vaginal itching, discharge or fishy odor, then you need to make an appointment with the doctor or visit the clinic and get a prescription for antibiotics. Take the antibiotics for the entire prescribed amount. This should treat the infection properly. Th doctor may want to do a vaginal culture as well to determine infection. In the meantime do not douche or sit in a bath, use powders. It is better to wear cotton underwear, and pants that are not tight.
You can take a good multivitamin with vitamin C.
