Moving the muscles in your hand can help pump extra fluid out. Try this: Start with your hand and fingers pointing up. Hook your fingers so the tips touch the top of your palm, hold for 5 seconds, then straighten them. Next, make a fist, count to 5, and release. Then bend your fingers so the tips touch the bottom of your palm, hold for 5, and stretch them back up. Ask your doctor what other hand exercises are good for you.
