I have a ring-shaped rash on the side of my vagina, and its been really itchy. I saw a skin doctor who gave me some medicine, but it didnt help. This started last October, and Im not sure how to get rid of it. Whats the best solution or treatment for this?

Sounds like you may be dealing with a fungal infection. To treat this, you can use an antifungal cream like Clotrimazole. Apply the cream to the affected area twice a day for about 2 weeks. Additionally, you can take an oral antifungal medication like Fluconazole 150mg once a week for 4 weeks to help clear the infection from within. Make sure to keep the area clean and dry, wear loose cotton underwear, and avoid tight clothing to help with the itching and prevent further irritation.
