I know exactly what you're going through.  Alot 
of times in the evening I have to either stay 
offline, or use IE instead of AOL.  As much as I 
love to chat with people, my hands are also 
really bad.  I have a muscle disorder that 
affects me from head to toe.  Took them forever 
to figure out what it was.  But, my arms and 
hands are the worst of it, and typing and driving 
really do a number on me.  Such a shame too since 
I make my living on the computer doing art, and 
my family lives only 3 hours away.  But since I 
cant drive, I usually dont get to see them much.  
It hit me the weekend before I left for art 
school, what a bum deal.  Take it easy, and try 
to keep your wrists in a neutral position.  I 
would suggest braces to wear at night :).  They 
take some time to get used to, but it will help.  
I get the tinglies sometimes, but mine is mainly 
lack of circulation...I have corpse hands!!!  
~~~X.x~~~  I hope they start to heal though, see 
you!  If you ever need any advice about it, feel 
free to ask.  I've had to deal with it for going 
on 8 years now >_<
