My husband came in from work today and has a rash that looks like a sunburn that tingles and itches. Its on his arms, inside of his thighs, on the sides of his torso and tops of his feet. He hasnt eating anything diffrent or been around anything that wasnt normal to him. I havent seen a rash like this before. I thought maybe he was allergic to something but the rash isnt raised and it is hot to the touch. Looking for some answers.
