<s>[INST] I run a low grade fever not over 99 degrees temp at night, a rash with tiny blisters that started on my chest (collar area) then it spread to first my arms and external vaginal area, then my legs and now it is getting on my face - it burns, feels like a sun burn and looks like I have been scalded; I am retaining fluid where the rash is. This has happened in the past. This started in August, seemed to be about to clear up, and then this past weekend it seemed to start over but worse. [/INST] Hi i think it is not a sunburn as unexposed areas are also involved.rule out immunobullous disorders.herpes infection.immunobullous disorders can be ruled out by biopsy and immunoflouroscence.whereas herpes can be ruled out by tzanck smear where u will find multinucleated cells.treat the condition with atarax 25 mg at night.antibiotic twice daily and use of wysolone 30mg tapered off to 10mg within one fortnight and application of gentisn violet for unruptured blisters and fucibet ointment for ruptured blisters </s>
