How long do canker sores last?

I’ve had them on my tongue before and they usually go away within a few days. This is the first time where I have one inside my mouth, below my lip. It won’t heal and seems to be getting larger. It’s been nearly a week. Anyone else have this? How long did it take to heal? Any remedies to help it heal?
