I strongly suspect I have carpal tunnel syndrome in my right arm.
This ought to be no great surprise. An entire lifetime spent using computers and in particular mouses could not help but have produced repetitive motions. And like a lot of people, I have posture that is not so good, especially while sitting.
About a year ago when the pain first started being noticeable, I didn't do much of anything about it. No pain, no pain. I tried to take it easy, tried to revive my experiment with voice-control for my computer at work, tried to rearrange my keyboard and mouse to hold my arm in different postures. None of it worked and probably some of it made the problem worse.
When it got to the point that I felt like I was losing strength in the arm, or at least that picking up things like bags of groceries was too painful to endure, I got a cast to wear while sleeping. It's comfortable enough but it seems to produce better effects in the morning only when I strap it on very tightly. This can make sleeping a bit uncomfortable, and it's off-putting, to say the least, to reduce my right arm to a nearly-useless club right before going to bed. It also doesn't do much for the pain below the cast line, down towards my elbow.
A bleg -- what other kinds of self-treatments can I do, relatively affordably and easily, that will alleviate the shooting jolts of pain and the sensation of weakness in my arm and hand?
