Getting massive pain in wrist, any options?

[WOWBOX40]

hm... wonder if there are any decent keyboard with a "scroll wheel on the left side of the keyboard: maybe its possible to bind f.ex the "1" key to both scroll up and scroll down (while also having the ability to use the mouse scroll wheel at the same time as normal). Maybe that would be more gentle for the fingers/wrist.

Or maybe some standalone external button which is a scrollwheel or a wheel of some sort, you can bind to the "1" key.
