Doctor, Doctor!

I've done something to my hand/wrist. I'm not sure what. A nerve from the base of my thumb all the way to about halfway to my elbow hurts. It hurts to turn it too far to the left or right. It is a little sore to type. I can't lift very much. It was hurting this morning when I woke up. In fact, I was gingerly twisting it to find out what I'd done and popped my wrist bone. So I kept popping it. I probably popped it 15-20 times before I finally just stopped. It would have kept on popping! How weird is that?

I have no idea how I injured it. I just know that it hurts. I've taken some ibuprofen.

Any doctors out there want to hand out a little free advice?
