Motion of fingers helps reduce swelling.
When you make a fist and extend fingers you actually compress tissues on the side opposite to the way you move try it, make a tight fist on your opposite hand and you see how the skin on the back of the hand and wrist is squeezed down. Wrist motion is good too once your wound can tolerate it. Talk to your surgeon times therapy is needed . Don't forget ice.
