I have been tanning for awhile now and the past few times I have been breaking out in a rash on my butt, above the crack and it’s causing it to welt. It’s blood shot red, hott as can be and burning and itching also really sore to where I can’t lay on my back. I’m curious to what this could be, kinda feels like a chemical reaction but at the same time how could it be when nothing else on my body is being effected. I do not but tanning lotion on my behind due to the serious burn I have gotten in the past.
