My vagina area has been itchy, dry &red. there's a red spot on my vulva, flat not a bump. i was prescribed antibiotics recently. what could this be?

Probably yeast: These symptoms are pretty typical for a vaginal area yeast infection, which can be triggered by antibiotics. Get in touch with the doctor or clinic that prescribed the antibiotic. They may want to examine you -- but depending on details they will discuss with you, might suggest you buy an over-the-counter vaginal yeast cream. In the meantime, don't worry. This doesn't sound serious.

Yeast infection: With recent antibiotic use, the most likely explanation is a yeast infection in the vagina. Try an OTC treatment for 7 days or see your doctor for the prescription pill, Diflucan (fluconazole). If the red, flat spot doesn't go away after treatment, get seen by an OB/GYN for further examination to determine what that spot is.
