A member asked:

Hi doctor, i have this blister on the edge of my mouth. i am having this for the past 4 days. can you please let me know what it could be..

A doctor has provided 1 answer

Mouth blister: A picture may be way more helpful than guessing without seeing it. Herpes labialis or commonly known as cold sore is a plausible explanation.
