Sprain is a common injury for all type of athletes. Moderate sprains heals on their own all you need to do is let it rest for few days atleast 48 hour to few weeks (depending upon its severity). Ice your wrist in order to lessen the swelling and pain, use of bandage to compress the wrist is very useful, and use of cast or splint to keep the arm immobilize for few days is beneficial, however use of splint for long time could have negative effect of stiffness of muscles.
