Okay so i have this blister inside my mouth on my bottom lip. it hurts really bad. and its been there for 5 days. what can i do?

Baby teething salves: Use this since it numbs the area and also check to see whether or not you have a sharp tooth adjacent to this irritation. Otherwise expect it to take about 2 weeks to fully heal.

Go to drugstore: You want to place a protective cover over your blister the pharmacy sells canker sore medicine if is still there after a few days later see a periodontist.
