REDUCE your usage. Many problems are caused by sudden increases in workload.

PROPER POSTURE is key. Make sure your keyboard isn't too high too low, 
there are reliable guides for ergonomics online.

Stretch GENTLY BEFORE starting - this prompts lubrication of the tendon 
sheaths. If you're looking for other stretching/strengthening ideas, 
look at what violinists and pianists do. They're heavy on finger/wrist 
action.

TAKE BREAKS. Stretch your wrists GENTLY during the breaks.

You should consider ibuprofin to reduce inflammation. Inflammation 
narrows already-narrow tendon sheaths leading to further problems. 200mg 
every four to five hours is fine. You shouldn't do this for more than 
two weeks.

You should consider icing to reduce inflammation. 10-15 minutes on, 
10-15 minutes off. You want to make the area that hurts cold, you don't 
want to freeze it.

DON'T rub your wrists. They hurt, but rubbing them won't help. The only 
thing in your wrists are tendons and rubbing will only bother them. 
Massage both sides of your upper forearm (or have a partner do it): this 
is where the muscles that control your fingers live. If they get tense 
or tight, that puts strain on the tendons, which inhibits their movement 
through the sheaths in the wrist, leading to inflammation.

I'm wary of the previous suggestion to get a grip-strengthening device. 
You do not need bulk-strength to avoid these problems, you need 
endurance-strength. That is, training to squeeze a hundred pounds of 
force 5 times isn't going to help. Being able to consistently squeeze 
at, say, 20-30 pounds might. When I had these problems, what ultimately 
helped me was wrist curls coupled with back/shoulder strengthening. With 
the wrist curls, I worked my way up from 5lbs to 10bs. Maybe fifteen 
reps flexing the wrist, fifteen extending. Two to three sets of reps. If 
you "don't have time" (and I didn't, to my detriment, for years), just 
do one set of reps. Be sure to do both flexion and extension - you need 
to engage the primary muscles and the antagonistic muscles or there will 
be problems.

Don't use too much weight. This makes your muscles tense. Tense muscles 
cause pain.

It is best to consult a physical therapist or other knowledgeable person 
about specific weight-training regimens.

In summary: correct problems with your posture and ergonomics. This is 
easy: do it. Reduce your usage - you have to work up to this sort of 
thing. Reduce inflammation now with ibuprofin and icing. Start taking 
breaks and, once you feel better, keep taking them. Once you get 
tendonitis, RSI, carpal tunnel, it comes back easier the next time. You 
have to be vigilant. Breaks are also good for your eyes - looking up and 
away to change focal depth. In the long term, it will be good to 
strengthen your wrists (this also strengthens your fingers) arm muscles 
and back muscles.

For best results act now. If you feel pain, STOP. Unless you let your 
wrists heal (and it will take a bit longer than you want it to), the 
problem will get worse. And if you get a full-fledged RSI, that can put 
you out of the game for months, or years. (I missed out on a career 
playing piano because of it.) Be good to your body.

Hope this helps.
