Chafing on labia

I have what I would describe as rug burn on my inner labia that I don’t think is from oral, but possibly from being rubbed raw on underwear afterwards. It’s the absolute worst pain I’ve ever felt and it’s been going on for about a week. I’ve tried aquaphor, but that didn’t seem to help. I put new skin (liquid bandage) on it, which has provided temporary relief, but does not allow it to heal completely. I am in a LOT of pain, and I don’t know what to do. Pleeeeaaase help!!!
