Hurt my wrist...what do you think the problem is?

It could be that the bone popped out of the joint (dislocated) or sprained. Worst case it it's broken. If you really are against going to the doctor wait a day or so but if it doesn't' get beter, you'll have to have it looked at. If it's just a sprain it will heal on its own, but if not you'll need to see a doctor..
