Blistery rash

I have a blistery rash on the tops of my feet and on the legs from the knee down.  It is very very itchy and seems to be worse at night.  I have tried Calamine lotion, Ivy Dry spray, hydrocortisone cream and Clotrimazole.  It seems to spread slowly.   I also have a few blisters on my upper back and lower back and now have a few on the tops of my arms.   Any suggestions?

A very very itchy blistering rash as you describe. I would rule out Dermatitis- herpetiformis (may be associated with coeliac disease and gluten sensitivity).
Best wishes

First you should consult a doc,make sure with diagnosis and investigations, diet or therapy would follow. Sometimes parasitic conditions like Scabies, or Cimicosis (Bed bugs) can be other causes to mislead!
Best wishes.
