This story resonates. A few years back I was dealing with mild pain while coding. I stupidly ignored it for months as it got significantly worse, to the point where it became impossible to type for extended periods. I tried lots of things. My doctor did a nerve conduction study, which apparently ruled out carpal tunnel syndrome, but he wasn't much help beyond that. He gave me some straps that I slept in and wore arou…
I don't have pain in my hands, but I get severe back pain from time to time. It's difficult to sit or stand (or be in any position, really) for a few days at a time. I can do some things just fine, like type, but I certainly can't concentrate long enough to do any programming tasks because the pain is so distracting.
When not going for some weeks (like when traveling) I can tell it becomes worse.
Plus you get in shape which is neat. I started out for health benefits but would be lying if I said I did not enjoy the visual benefits. :P
