Wrist problems can often be traced backed to the rider having too much weight on their hands. The aim of a good bike fit is to get close to no weight on your hands. The classic way to check this is to put your bike on a trainer, and see if you can manage to pedal with your hands held about 1 cm above the bars i.e. without falling forward onto the bars.
If your handlebars are too close, you will have too much weight on your wrist and will fall forward - and will need to either move the seat back on its rails (if there is room left), or get a longer length stem. If you have too little weight forward (unlikely), you'll be able to balance with your hands much further up and back from the handlebar. That's not good either, as too little weight on the front of the bike adversely affects steering and braking control.
If you don't have a trainer, you could try an experiment on your bike on some flat ground where there's no traffic around to smash you should you get out of control. You could also try thecompetitivecyclist.com fit calculator - and see how your current bike matches the top tube/stem length recommendations it gives.
Using a compression bandage on an injured wrist would be helpful (RICE = Rest, Ice, Compression, Elevation) - but you really need to identify the cause of the trouble rather than just treat the symptoms.
Of course, for a proper diagnosis, you should see a doctor and perhaps consider some physio to get things back into ship-shape.
