Hang in there...it will go away like everything else. It just takes time.

Things you can try....put an ice cube in your hand. The cold sometimes breaks some of that.

Do you have any video games that are interactive that require concentration? The active Wii games are good for this. I've used DDR. They require concentration to do them. You'll suck at the beginning...that's expected, but don't get frustrated and keep at it. It should help; you're being active and getting your blood flowing and you have to concentrate to do it. If not, come up with something else. Maybe look online for a pattern for origami or how to make paper airplanes and try to do them. Something that requires concentration but won't hurt anyone if you screw it up. Just don't get frustrated.

Just avoid doing anything really important until it goes away a bit. I understand....
