Stubbed my finger

[Jkayworld_18]

I stubbed my finger playing with my dog. My pip joint on my pointer finger is in slights pain when I apply pressure or bend it to a certain extent. There is no swelling, redness, or bruising. It does feels stiffer than usual but isn’t in pain if I hold it still. I’m wondering if this is something I need to get checked out or will it heal on it’s own.
