Hello, and I hope I can help you today. Jock itch in a woman is actually a topical yeast infection of the skin. This same type of yeast can also in fact the inside of the vagina, causing itching, burning and irritation. If you have vaginal symptoms, the infection also needs to be treated inside the vagina. Treatments for vaginal yeast infections can include creams, suppositories, or oral medications. All of these in most countries can be purchased over-the-counter, but the medication should be designed for treatment of a vaginal yeast infection. The correct type of antifungal medication should also have the suffix -azole at the end. Examples are miconazole, clotrimazole, and terconazole. Usually the creams or suppositories are designed for use for 3 to 7 days. So in summary, I recommend that you use a treatment for vaginal yeast infection, and until you complete using the medication and no longer feel irritated and red I recommend that you not have sexual intercourse. Sometimes partners of women who have vaginal yeast infections can also get jock itch and give the infection back-and-forth to their partners. There are over-the-counter products usually powders or sprays, that are designed for men to treat jock itch as well. I hope I was able to adequately answer your question today, and that this advice was helpful. Best wishes, Dr. Brown
