A member asked:

My 4 year old son developed an allergic reaction to something. it's all over his hands legs head and face. he didn't eat anything that will cause this or play in grass. it just came up. used calamine lotion but it isn't helping. what should i do?

A doctor has provided 1 answer

Diphenhydramine: A rash/hives in diverse location suggests an internal response to something. This can certainly be a food, but it could be a new seasoning in a food or a food he just became allergic too. It can also be seen as a stage in some illnesses or bug bites. Skin lotions seldom help diverse rashes. Diphenhydramine (Benedryl) is OTC in the US & has good anti-itch benefits.
