Help.

So I used nair the other day down around my butthole and private area, I wiped it off after the amount of time the bottle said and then I showered well, today I noticed my butt hurts some around where I put it so I looked and I have red spots almost like a rash. I don’t know what it Is, I can’t post the picture because it reveals too much of my private area, but it really hurts and I’m wondering if it’s from the nair or if it’s something different.. please help
