HELP!!! rash! please help

Okay, so I have eczema, and when I was little I had it on my crotch. I've had the symptoms like I did when I was little again so I figured it was the same thing. It's a pinkish read itchy slightly inflamed rash right past my vagina opening to my butthole. It got way worse when I shaved again after getting waxed for half a year. I know they're razor bumps but on top of the rash it's becoming a little concerning. Any advice please!
