Swollen Hand, Unable To Make Fist Following A Fall. Should I Strap It For Support?
This sounds to me like muscle or tendon pulling with joint capsule contusion.
This caused swelling and inability to extend wrist. It is important to see is this caused by swelling and pain or there is a nerve damage. If you cant extend or bend your wrist at all and you have loss of sensation in fingers this can be sign of nerve damage,but this is very rare in such injuries. ALso be sure that you feel pulsatility in radial artery.
YOu should only rest with your hand, put some cold compress on it, hold it in elevated position and take some nonsteroid painkillers. There is no need for strapping it except if you cant avoid working with this hand.
Hope I have answered your query. If you have any further questions I will be happy to help
