I do not have an answer for you. However, if you figure it out, would you mind emailing me please? I have the exact same thing, but no one else in the household has it. It's very itchy, been to the doctor 3 times. They feel it's an allergy and have put me on allergy meds and also prednizone, but... after two weeks, it's still here. Starts out looking like a misquitoe bite, then forms a water blister on top of it. It itches so much. I have them over my whole body now and the ones on the legs have been itched so much they resemble chicken pox. Doctors are now thinking an auto immune disease of some sort... I go to dermitologist in one week. They have ruled out chicken pox, scabies, liver disease (itching), bug bites and now are looking at a specific allergy or auto immune disease. Please keep me posted and I will also keep you posted with what I find out. Email is: dswyffels@hotmail.com
