A friend of a friend has spina bifida, she ambulates with crutches and has developed CTS in both wrists. She's scheduled for surgery on the first hand in a couple of weeks, and they're telling her that they can do the second hand three weeks after that. She must put at least as much pressure on her wrists walking, as any of us do riding, and probably more.

I assume you've already corrected your ergonomics and tried conservative treatment. I know way too many factory workers who've had CTS surgery five or more times on each wrist.
