Hi, 5 day s ago I got a really bad sunburn on my back, butt, and the back of my legs. Last night my butt started peeling, I didn t peel it but it hurts really bad, and I have a long red line from where it was peelinh and it feels really rough and hurts to sit on my butt. How do I treat this to make it go away? And will there be scaring?
