Thanks for writing to us.
Burning micturition with fever
, and multiple blisters all over body could be due to an STD like Herpes
, urinary tract infection
or a skin allergy- dermatitis
A physical examination and serological tests for herpes are needed to find out the exact cause.
The treatment will depend on the cause.
I hope this information has been both informative and helpful for you.
