If you wear a ring on the affected finger, you should remove it. This will help reduce any swelling and pain. Try to keep your hand raised until a doctor sees you. You'll need to have your finger splinted. Go to your nearest minor injuries unit as soon as possible if you think you have mallet finger. It can also happen after catching your finger on something. In some cases, the tendon does not tear, but a small fragment of your finger bone breaks off where the tendon is attached. Your finger will also be painful and swollen.
