I think I may have chipped a bone or some soft tissue damage in my hand.?

I had a temper tantrum a little over a month ago and punched my VERY hard dresser. I'm having chronic soreness on the knuckle-end of my 4th metacarpal and am afraid that I either chipped the knuckle or have done some soft tissue damage. It doesn't seem to be getting any better. I'm curious, if there is a small chip of bone floating around in there, will my body eventually consume the chip or would it have to be surgically removed? Is there a cheaper way than x-rays to tell what the problem is. Probably not, but any advice (aside from the obvious "stop hitting stuff") would be welcomed.
