What Is The Treatment For Black Eye And Lump In The Cheek?

I was practicing softball with my adult coed team and I was in the outfield, tonight. I ran pretty fast to catch a hard hit pop fly to centerfield and while I was lining up to catch it, I got hit with the ball, right under my eye. I would say the impact was on the cheek and the side of the nose. I put ice on it. It feels like there's a circular lump on my cheek, now, but the vision in my eye seems okay. It is getting discolored, looks like it will be a black eye. Should I seek treatment tomorrow or just keep ice on it?
