A member asked:

Is it normal for my lower lip to still be swollen and tender where my canker sore is almost healed?

Yes: These things heal from the inside out, and usually take up to two weeks to go away completely.

Possibly: See your dentist for diagnosis and treatment options. It may not be a simple canker sore or it may be secondarily infected.

Probably but....: It's most likely still in the healing phase and within normal limits. The only way to know for sure is to see a dentist who can determine that.
