I have a HORRIBLE canker sore, is there any way that I can make it less painful?

I've had this canker sore for about 1 or 2 days, it's on the inside of my lip, near my bottom teeth. It's so painful that it hurts to talk, or eat anything. I've been putting baking soda and gly oxide on it, but it's not helping that much, It feels like a hole in my lip when I touch it with my tongue. Can anything help?
