Numbness is almost always the result of a pinched nerve. This is most likey from your ulnar nerve which runs through your wrist and elbow. It could also be due to carpal tunnel syndrome which is most likely the cause of repetative movements of your wrist.
Ice is good as is resting it as much as possible, so the splint is good too, as long as you release it periodically for wrist range of motion so it doesn't stiffen up on you. If this doesn't help, you will want to get further testing, and may need surgical intervention.
