Sorry to hear of your pain Beepster.  I where an armband for Tennis Elbow but I don't play tennis. It is for long periods of computer use.  Here's the type:

I also use a vertical mouse like this:

These two items do help the nerve pain a lot. 

Thanks, man. I'm a lot better than I was a few years back (I could barely move back then) but still a long way to go until I may be able to live somewhat normally. This is why I've gone so nuts on learning the DAW stuff. Keeps my mind busy and will hopefully lead to a bit of extra income at some point. I absolutely can't stand just lounging around and not working towards something. I am finally getting some attention from the right doctors so things should get a little better and the "down" time has allowed me to acquire the skills/knowledge I never had the time to back when I was gigging/working non-stop.
 
That mouse looks cool. I use trackballs and trackpads mostly which help a lot (and I preferred them even before I was all crippled up) but I'm always looking for new ways to do stuff and that looks like it eliminates the major issues I have with regular mice.  Honestly I think standard mice are an awful design and strike me as being one of those things that are only in popular use simply because they've been around for so long (kind of like Pro Tools... sick burn! lol).
 
In fact that might be a good thing to pick up until I can afford a new trackball. THe scroll-ring on my Expert Mouse (trackball) is totally dead and it makes certain things in Sonar very annoying... particularly trying to navigate in the Inspector. I keep requesting they allow optional scroll bars on every section of the program but since most people have a proper scrollwheel I doubt it will ever happen.
 
Cheers and I hope you can keep your pain at bay as well. It sucks.
