<s>[INST] I have a rash that appeared 3 days ago in a small patch on the right side of my stomach.  I then got a patch on my left side and now have it on my groin area and a few spots around my belly button.  The rash is tiny red dots that look like pin pricks.  I don't feel unwell, but am slightly concerned as it appears to be spreading. [/INST] Hi rash on the dtomach spreading and pinprick like  lesions can be milaria or papular urticaria.papular urticaria is very rare in that area.Milaria is due to excessive sweating all over the body.it can be cured by atarax 25 mg at night .alaspan in the morning vitamin c tablet and application of calamine lotion can cure the condition.If no response start a antibiotic to rule out maculopapularr rash </s>
