HI...your doctor is right Herpangina is a self limiting viral illness. But sometimes it can take 1- 2 weeks to settle. But Herpangina blisters will only be there on the soft palate. But if you are seeing blisters on the hands and feet then it could be Hand Foot Mouth disease. his 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.
