I have a huge,painful cold/canker sore on the left side of my cheek, any home rememedies/solutions?!?

The best remedy is wild oil of oregano from the health food store. It will also get rid of gum/tooth abcesses! Second best is a half/half solution of mouthwash and hydrogen peroxide -- hold it in your mouth for about 30 seconds -- do 2 treatments back to back. Just don't swallow it... You can also put this on a cotton ball and hold it over the area with your tongue. Good luck.
