My lip is super swollen from what i belive is a canker sore. is there anything i can do?

Ice : If your lip is swollen, place ice on it to reduce swelling and lessen pain. The canker sore will go away in about a week.

Canker Sores: are the most common oral lesions. Individual ulcers typically last 1-2 weeks. The condition is usually self-limiting. Try to keep adequate oral hygiene as possible. If concerned see your dentist after 10 days.
