Finger still swollen after door slammed on it?

Icepack the finger, 10 minutes packed; ten minutes free. You can also take NSAIDS -- NOn-Steroidal Anti-Inflamatory Drugs like aspirin, acetaminophen or ibuprofen, to reduce pain and swelling. Carry the extremity above the level of the heart to keep swelling down. If you think the finger may be broken, head for a hospital and get it xrayed. Do not pull on the finger. If moving it hurts -- stop moving it. There's no way in the field to tell for certain if it's broken or sprained (unless you can see the break). So leave the finger immobile.
