Hello,
Without examination, confirmation of a diagnosis is tough but it can be due to contact dermatitis,sweat dermatitis or heat rash.

Wash the areas several times with fresh water. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin if the blisters itch.

If still the symptoms do not improve or turn painful then please get a clinical examination done by a dermatologist. Herpes blisters have to be ruled out.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
