Four weeks ago I noticed a couple of small red bumps on my arms and thought they were mosquito bites. I then developed a sore throat for 4-5 days and an upper respiratory infection thereafter. I felt lethargic but was able to continue my daily routine. Then more bumps on my arms and then very quickly a large amount on my thighs and down my legs - even on my feet and the backs of my hands. My torso had very few at first but then a week an a half later started getting them on my chest, stomach and back - smaller and fewer than on my arms and legs though. The older ones have dried up and started to heal (although the skin is still bright pink where the spots were) but I continue to get new bumps - even a few on my face (forehead and bridge on my nose). I have seen two doctors who think it is some sort of virus but were not able to provide a conclusive diagnosis. One gave me a course of Prednisone. Other than that I take lukewarm showers, apply calamine lotion every night and try not to scratch. The itching is not terrible - more from the bumps drying out than anything else. From what I have read on-line I believe I have PR even though I don't recall a specific herald patch. I sent photos to YYYY@YYYY . Do you have a recommended course of treatment?
