my daughter is at the hot beach, very fair skinned (has italian/irish, but more irish pale skin with brown hair/eyes) and wore sunscreen but now seems to have a heat rash? not itchy, uncomfortable, ugly, bumps, on back of her legs, some on top of feet and arms. i m sure from laying out in hot sun. could be from the SC beach water/sand. She put aloe on it. has some cortisone creams. took tylenol. but now she says it looks more dark reddish/purple but not spreading. i told her to take an epsom bath if they could get to the store. could it be anythign worse? i had sun poisioning once, where it looked like i burnt my skin, under the skin. could that be it? what should i do? of course i m 8 hours away! thanks
