What could cause a tiny bump on my lip?

The bump on your lip could be a cold sore, also called a mouth sore. It is called by bacteria and the body attempts to get rid of it by covering it.

You may have bumped your lip on something causing a small bump and slight swelling. You could also have a small cold sore on your lip. If it's a cold sore it will probably get bigger before going away.
