So I did something stupid awhile ago and punched a hard surface pretty hard out of rage. Well my knuckle has been slightly swollen for weeks now, and I can feel something move on the tip of it when I put pressure on it like its lose.

The reason I'm asking here first before sitting at the hospital for 8 hours is because I feel no pain or anything and my finger works just fine. Just wondering if I might have chipped something and is it even worth getting it checked?

Thanks.
