What can I do about a blister on my arm?

I feel asleep while using a Heated Back massager abd when I woke up I had a blister the size of a raisen on my arm. It basically looks like stretched skin bubbled up but half of it looks deflated. What do I do I’ve never had a blister before?
I’m going to the doctor tomorrow. Should I just leave it alone and ask about it then?

Make sure to wash it with cold soap and water. Put a bandaid on it so the open sore doesn’t get infected. It should be okay. If it looks worse than a simple burn get it checked out by the doctor. Aloe will help prevent scarring.
