If I had known about this 14 years ago I would have certainly tried it, I tried many things... the ones that I think were helpful for me are:

Ice bathes for my arms: I filled a sink with water and ice and submerged my arms up to the elbows; this was obviously useful for short term pain relief, and might have helped reduce inflammation over the longer term. It was important to wait until the arms were warmed up again before going back to typing.

Keeping fingernails well trimmed; surprising, but it made a big difference.

Massage; I think it was through massage that I started realizing that even though my symptoms were in the wrists the problem was probably more systemic, it's amazing how much pain a good massage can discover in surprising places!

Stretching; stretching the wrists felt immediately good, as did standing in a doorway, arms on the door frame, and leaning forward. Working on the hamstrings probably helped longer term.

Weight lifting, particularly exercises that strengthened the back; lots of people have mentioned it here, and I credit this for being the biggest long term help.
