How should I heal my wrist after a severe sprain?

RICE. Rice stands for rest, ice, compression and elevation. If the sprain does not get better after a few weeks, it is wise to see a doctor to make sure there is nothing more serious going on with the wrist.
Ice , splint, rest. When wrist injury occurs apply ice 3 times a day for 20 mintues for first 48-72 hours. This help to decreased the inevitable swelling from theinjury. Between application of ice pack a rigid wrist immobilizer should be used continuously. Most of all do not use the affected wrist. The more the wrist is used the longer healing will take.
