Should I do anything in particular post De Quervain’s surgery?

Rest and elevation of the hand is important and will also help reduce discomfort. If fitted with a sling, take your arm out of the sling hourly to exercise your shoulder and elbow so they do not become stiff. If your fingers and thumb are not in the splint, they should be moved as well. At night sleep with your arm propped up on pillows next to you.
