I absolutely hate getting a canker.

I've had two in my mouth since the weekend.
The one on my top lip is trying to set a new record for pain and girth.

I've salt watered the hell out of them... no change
I've mouth washed the hell out of them... no change

Today I finally decided to go the extra mile and use rubbing alcohol. It hurt like no pain I've ever felt, but those fuckers seem to be learning!!

Cross your fingers for me that when I wake up, they'll be on their way outta there.

[addendum]

Well it hasn't gotten better one bit. Are you sure you have been crossing your fingers?
