Mouth Blood Blister



I experienced a trauma to my upper lip and now on the inside of my lip is a large blood blister. How do I treat it and how long will it take to go away? Thanks


Typically there is no treatment necessary. It will go away by itself within 7-10 days. You should see it get smaller each day.
