Lots of blisters at top inside of gums help Im in alot of pain? - blisters on gums

I mean, many bubbles and think they are in the top of my gum, which are very painful and could not sleep the night before.
I have tonsillitis at the moment, and I have today about the fever. Chills and headache.
What could this be and how to heal so much pain
