I had exactly the same problem. Heavy tendinitis in my right elbow, mostly due to a regimen of squash, badminton, and rock climbing multiple times per week.

I similarly switched to trackball mouse and keyboard without num pad (I was already on vim).

But what helped me more than anything was a keyboard tray that goes below the desk, almost on your lap.

Whenever we move offices at work, it sometimes takes a day or two before the tray is installed and I notice that the discomfort starts coming back quickly.

I had a very similar experience. I stick to a 10 keyless keyboard (no numpad) but I gave up on the trackball. I use a wireless trackpad now because I ended up with pains in my thumb after a couple years of the trackball. I could probably have used a better quality trackball but the selection is/was limited.

vim support in IntelliJ is pretty good these days so that's a huge help too. I had to abandon emacs and my claw movements early in life...

Thanks for the “lower the keyboard” tip. I’ll try it out, although most likely will be raising my seat.
