Even though I have nerve and tendon damage, the symptoms are very similar to CTS, so I hope this can be of some help to fellow sufferers. A couple of weeks ago I bought a throttle rocker (RRP $7.50) and have had about 90% pain relief when riding. \/ It took a couple of rides to get the hang of it but I am out there riding more because I am not in any real pain and thoroughly enjoying riding again, relatively pain free (in the right hand, anyway) It's a little moulded plastic gizmo that clips over the throttle and extends to rest your wrist on. With this support you use a combination of (less) wrist and more palm (of hand) to twist the throttle and not so much wrist action. This was a really cheap solution for me, because I was going to update the bike because of it. I have already put handlebar risers on to try and get more upright. I let my sister-in-law try it for about 40km (my hand and wrist was killing me in less that 3km without it) and she's getting one now too. I hope that it can be of help to others, but for the RRP of $7.50 if it doesn't work it is no great loss.
