It : It is possible that you have both herpes and a yeast vaginitis at the same time. Usually yeast vaginitis is not a painful problem, which makes me wonder about the herpes infection you mentioned. You relly need to see your family physician or gynecologist soon to sort this out and get proper treatment. Until then take some Ibuprofen or tylenol (acetaminophen) to control some of the pain.

Sounds like herpes: Severe yeast infection could do this, but this sounds most like herpes -- and since herpes is on your mind, you may be at risk. Penicillin is useless against either herpes or yeast. Monistat will help yeast but not herpes. You need to see a doctor ASAP, the sooner the better both for accurate diagnosis and because if it's herpes, treatment must be started early to be effective.
