This is something for which you should see your GP, and preferably a dermatologist.
There are a number of causes of such recurrent blisters:
Bullous Impetigo: this is an infection by staph bacteria that causes such blisters
Drugs: some medications like barbiturates, furosemide, etc can cause such blisters
Autoimmune blister causing conditions:
- epidermolysis bullosa acquista
- IgA-mediated bullous dermatoses
These are some of the likely conditions for you.
Note down these conditions and discuss with your GP.
You may need further tests and investigations.
Discuss with your GP whether you should be referred to a dermatologist.
Meanwhile, do not prick the blisters. Do not rub them. Keep the areas clean.
But do show your doctor at the earliest, this is something which needs a doctor's examination.
I do hope I have been able to clarify the situation for you and help you in knowing what to do next. If you need more help, please let me know so l can continue to assist you.
Thank you and I wish you the best of health - stay safe!
