<s>[INST] My 7 yr old boy had a few red pimple like rash on left leg. and couple in right arm. Took him to the doctor and told us its chicken pox...should go away in four days. Although those pimples have it s pimple head dried off, after four days new ones appeared on same leg, four more on right arm and some few small tiny ones on buttock. What could possibly be? Thanks! [/INST] Hi, thanks for your question. it looks like folliculitis, a form of bacterial  infection of skin which can be treated with application of local antibiotics like mupirocin. if your child didnt had fever before the onset of rash it is unlikely to be chicken pox. </s>
