There is a chance that they are still just real sore from falling. It could also be possible that you have some kind of nerve damage. If so I'm pretty sure you will be okay, but it depend's to on how long ago you fell. If it get's worse, or if it's been 7 day's or more you should call your doctor. It could be just about anything. Feel better.
You ulnar nerve runs proximal distant along your ulna. That's why when you hit your elbow you get the tingling sensation. If it continues to tingle, you may have some minor nerve damage that will heal with time. If you still have full mobility of your hands, and feeling in your finger tips than you will be fine.
