I Had A Basketball Game Last Night And I Played

I had a basketball game last night and I played all four quarters. After the game, the right side of my chest hurt. It hurt to sneeze or laugh the rest of the day. I could take deep breathes though. The next morning when I felt my chest, it felt as if it were a bruise in the center and the pain was no longer the right side. It continues to hurt when I sneeze aswell. Will this wear off? Or should I seek medical attention?
