I Have A Burning, Stinging Itching Vulva. Also There Is

I have a burning, stinging itching vulva. Also there is a "crawling" and "bubbly" sensation. This is the 3rd day. I see a red rash but not sure if this was caused by scratching, although trying not to do that. Just had a yeast infection 2 weeks ago and though was cured. This is much more intense. Thank you.
