I am pretty familiar with the inside of my mouth so I know this is new - must've developed quickly over no more than a week. I'm thinking it's probably a blood blister but it has no pain and I don't remember biting my cheek, obviously could've happened in my sleep. It appears to have a small blood vessel connected to it. Border is pretty darn consistent.

A little freaked out and want to know opinions on if I should get it examined ASAP.
