Hello,
You are suffering from severe body itching. Your symptom may be indicative of
pruritis,
contact dermatitis, shingles or nerve problem. You are suggested to take antihistamine at bed time, it will reduce the symptoms of allergy. Do not touch, pick or scratch. You should apply ointment
hydrocortisone on the area affected. Wear loose fitting cotton soft clothes, take bath regularly with normal water and apply moisturizer.
Get clinically examined by a
dermatologist. Get
complete blood count, liver and kidney function, T3, T4, TSH, done to detect / rule out pruritis, dermatitis, etc. To rule out / detect shingles your dermatologist will take tissue sample or culture of the blisters to send to the lab. You with be accordingly treated if tests show positive reports.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
