Lump on outer part of lip (looks just like a canker sore but not IN my mouth) after biting my lip... what is it & how do I reduce swelling?

So I bite my lip last night and woke up this morning with what LOOKS like a canker sore except on the out part of my bottom lip. I don't get cold sores and I know it's not turning into one because my older sister and both grandparents get them and I know what to look for....

this lump isn't a group of small sores or anything, it's just one sore and it's right in the middle of my lip and I really want to know the best way to reduce the swelling of it and know what it is...
