well i have a really bad sunburn right now too. i use aloe vera and it helps release the pain. you can normally find in in your local drugstore. hope this helps!
(Ivie88 says) I too have a sun burn and it is really bad. If you take some vinegar and a VERY little bit of water on a cottonball and dabb it onto your sunburn... it REALLY helps! Aloe helps too, if that doesn't work then use the vinegar! Good luck with your burn! (BTW mine is so red moving my arms hurts. and if i go to bed i have to lie down and NOT move. I put my arms by my side and put my head on the pillow! Good luck)
