I've also suffered with shoulder problems initially caused (I suspect) 
through use of  a mouse almost at shoulder height through my teens. Our 
PC was in a cabinet by the dining room table and this was where the 
mouse ended up. After doing the initial damage I'd struggled with using 
a normal mouse at work, in spite of being in a far more normal position. 
I switched to a trackball about 3 years ago and the problem has been 
significantly reduced.
I did see a doctor about it, I was told it's a trapped nerve and they 
can't do anything about it.
I use a Logitech TrackMan, originally had a Microsoft one but found the 
ball tended to stick.
