Squashed Finger or Toe
What to do first: If the digit is deformed, the nail is coming up, or there’s blood under the nail, see a doctor. Apply an ice pack or run under cold water to ease swelling. If the wound is bleeding, clean it with soap and water and put on a bandage.
What to do next: Over the next 72 hours, watch for increased pain, swelling, redness, drainage, or fever. These symptoms can signal infection; see your doctor.
What not to do: Don’t attempt to straighten a fractured finger or toe on your own. That’s definitely a job for a doctor.
