<s>[INST] occuring common type of pimples on a kid s knee. these pimples had occurred just before 4 days after fever. He gets fever often I mean atleast once in a week. His stomach is very big even though he don t eat much. So please let me know what disease is it. He also vomits sometimes [/INST] 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.Regards - Dr. Sumanth </s>
