Ever since I came home from a two day beach trip, my arms,shoulders, hands, lower half of my thighs and legs (all areas exposed that were exposed to the sun), have received something rash-like. (I am brown skinned, so I just got darker) This "rash" is extremely itchy and burns/stings every time I place body lotion on it. My arms especially are currently itchy, bumpy, dry skinned, and flaky. I'm not sure what to do or what this is...
