Hope you are feeling better.
I'd also see the chiropractor. Your neck could need adjusting. I will get pins and needles and all sorts when my neck is out. Sometimes waking in the morning with totally numb hands.
and it's just my neck. :)
arm symptoms and is more common than you would think. I had hand
surgery a few years ago and more than half the patients in the prep
area with me were there for surgery to correct it. [ Thats a last resort
fix , so even if you have it you probably could improve with physical therapy.]
Also agree that it could be a neck problem.
I think there might be credence to the lack of hydration thing. I definitely notice this more in the winter when I'm not sweating as much and thus not drinking as much water than in the summer when I'm sweating plenty and drinking plenty of water.
If you type with your left hand , even though you use your right more
it could still happen. Oddly, it can come from any activity where your
wrists are in a strained or overused position . Most people associate it with typing. Here's a strange one for you : My doc had a patient who

Its probably not the cause of your problem. Just thought i would mention it.
it creates numbness, or rather, constant pins and needles, in the middle fingers and a failure of message to get through to the nerves. So you are telling your hand to clench, but it won't. It just won't.
The pain in your wrist when you work with it is quite searing and unmistakeable. So you might start pruning thinking you are okay, but by morning tea time you are in really bad pain and the noise of the pain seems to shut off the tunnel to the nerve message, and you become weaker and weaker and you just can't do the bigger cuts, until you can't do any cuts at all.
There are tests they do for carpel tunnel, basically electrical tests. They wire you up at the shoulder or elbow and at the finger, and then give you electric shocks and measure what gets through. It doesn't hurt.
I hope it's not anything more serious.
