Hi. Welcome to JustAnswer. I shall try my best to assist you while you are corresponding with me.
How long has this been happening for?
Please enter chat and use reply to respond.
approx. 4 weeks
Are you on any medication for a previously diagnosed medical condition?
Rampril for some years, omeprazole for approx. 3yrs. paracetamol and codeine when req. for a back and hip problem.
Alright, what parts of the body is itching and where do the blisters develop?
all parts of torso, not a rash just odd spots.
Is there a sharp, tingling pain over the area that develops blisters?
Yes. Also sudden painful itch can appear any part of body.
Have you ever had chicken pox? Or have you been immunized against it?
Had chicken pox as child.
Alright. Do you have a picture of the blister?
Sorry ,no. But it is very similar to chicken pox spot.
Okay, if you have had chicken pox as a child then the only variant of the virus that can cause a rash is Shingles and that occurs as a patch of small blisters on one side of the chest or any other area, but there is only a patch since, it affects what is called a dermatome of the body (a particular area supplied by any sensory nerve).
This seems more like Dermatitis or Pemphigus and this warrants attention of a Dermatologist rather than be on just anti itching pils.
Only one spot in any given area. Only few spots on torso well separated.
I will talk again with my G. P. Thanks
Yes, that goes consistent with an infectious or an autoimmune etiology rather than a viral disease or an allergy. With allergies the rash is macular (raised red patches). Blisters or vesculopapular spots are usually seen with bacterial infections or in autoimmune diseases such as vasculitis.
