Hi, I Have A Extremely Red Vulvar Area And Burning..

Hi, I have a extremely red vulvar area and burning.. I have done an over the counter UTI test, negative and a over the counter yeast test negative. No temperature. I have a heavier bottom area and get irritated easily. I have used a cream that starts with a Cordi(something). It was a prescription. It was more than one cream combined. Very effective. Can you help me to figure out what it is called, so if I call the pharmacist, to see if I might have a refill, he/she would know what I am talking about. I recently threw away expired, medications. Thank you in advance if you can help.
