What Causes An Itchy Rash On Arms And Legs Of A Child?

My 9 year old son has a rash on his arms, top of hands, legs and top of feet only. He says it itches a little bit from time to time. In some areas its one big red spot and then starts to scatter into smaller spots all over.To me it looks a little bit like hives but I am not sure. He hasn t come in contact with anything out of the ordinary in the past couple of days. Please tell me what you think it might be and should I keep him home from school tomorrow? Thanks for your time, Confused and Concerned mom

Hi...I feel by what you quote he should be having a - Hand Foot Mouth disease. This is one viral illness among all other exanthemas which can cause fever followed by rash over palms and soles. It is a self-limiting disorder and itching can be really worrisome. I suggest you use any over the counter antihistamine if you have one with you now. You can use Hydroxyzine at 1-2mg/kg/dose (Maximum 10mg) every 6th to 8th hourly for 7 days.
This can even cause some peeling of skin in the next 4-6 weeks and do not worry about it.
