The hand is often at risk from a direct blow such as in hockey or an athlete can land on the hand after a fall from contact sports, these types of blows mostly result in a hand fracture.
If the hand has suffered a fracture, that is a bone or bones have been cracked in the hand, there will be pain and swelling to the hand and the hand will not be able to move.
TREATMENT AND RECOVERY
For a fracture of your hand you should see your doctor. To relieve pain immediately after injury, apply ice over the injured area for 15 minutes using a thin towel between ice and skin to prevent ice burn. Also make a sling to immobilize your hand keeping your hand up to control swelling. Try to move your elbow and arm as much as possible because if they stiffen up it will delay recovery to your hand.
