I noticed yesterday that my child had red blotchy areas on his cheeks when we came in from getting out of
the car. He also had areas that looked like a fresh moskito bite on
his knuckles of
his hands and he was scratching them. Then an area on his ankle too. After about an hour this all went away. No rash on arms, hands other than knuckle area, truck or legs. Today he went outside again today from one house to another and the rash has come up again. What could this be.
