I Bit The Left Side Of My Bottom Lip This

I bit the left side of my bottom lip this afternoon . There was a slight swelling. I rinsed with warm water and salt. Swelling went down and came back. I rinsed with warm water and witch hazel. Swelling went down and came back. I put ice on it and it seemed to get worse. Left side of my mouth (cheek) and lip, but more of my lip. I took a Naproxen 500. The swelling seems to be going down but looks a squirrel with a jaw full of acorns. What do suggest I do to bring this swelling down? Thanks
