Help I have a rash

I get this rash on and off mostly in the summer and then it completely goes away. Last week I had one day of bleeding and then it pretty much stopped and then just had a brownish red/pink discharge and then that stoped. Fingers crossed it was baby dust. Well right after that this rash appears. It hurts. Burns and itches. My face also is peeling and burning. Like all at the same time. I can’t hardly take it. It’s very warm and sweaty and it seems to be the WORST I’ve ever had. I’m miserable. Anyone have an idea. I was thinking maybe a yeast infection. But like I said, I’ve never seen it like this.
