Hi. My whole body is itching & I ve got two lovely rashes. Started as a spot 6 days ago, spread to legs, other arm, neck face & belly, creeping onto chest. Tried showering & treating with topicals. First rash looks a little like erythema multiforme pictures. Second rash looks like contact dermatitis pictures. Got a shot of 50 mg Benadryl & 40 mg Solu-Medrol at 11 am @ Urgent Care; back to itching by 5 pm. Hasn t responded to benedryl, allegra, hydroxyzine, topical steriod creams fluocininide or betamethasone. Only other symptoms are fatigue & headache. Got any ideas what this could be or what I should do to help myself?
