What Are Treatments for a Smashed Finger?
In most cases, smashed fingers are mild and can be treated at home. There are a number of things you can do to treat your injury, though be aware that if any of the above serious conditions exist, you will need medical treatment.
1. Immediate Treatment
- Ice the injury. Icing the injury reduces swelling and can reduce bruising by slowing the bleeding into the affected area. Keep the ice on your finger for about 15 minutes at a time over the course of the first few hours. Keeping ice on the affected area for too long can lead to frostbite.
- Elevate the injured finger. Holding your smashed finger up reduces blood flow thus reducing swelling and pressure. Don’t dangle your handafter you have smashed your finger.
- Move the injured finger. Be sure to move your finger gently. There may be some pain and throbbing but make sure to move it. If you cannot move your finger, then you should seek medical attention.
- Use over-the-counter medications. Taking a pain reliever such as ibuprofen or acetaminophen will help with minor pain and swelling.
Note: If you have a torn fingernail as a result of the injury, carefully clip away along the torn edge. Keep a bandage over the injured fingernail to protect against infection. For the next 7 days after removing the bandage, soak the affected fingernail in a salt water solution (1/4 teaspoon of salt to 8 ounces of warm water) at least once a day.
2. Medical Treatment
If there is blood under the affected fingernail and pain has increased, call your doctor. The doctor can guide you through a simple procedure you can do at home to relieve the pressure and prevent the nail from falling off. The procedure is as follows:
- Clean the injured finger.
- Unbend a metal paper clip or other similar piece of metal wire.
- Hold the paper clip with a pair of pliers and place the end into an open flame until it is very hot.
- Touch the hot tip of the paper clip to the injured fingernail where blood has pooled and the heat will burn a small hole into the nail.
- When the paper clip is removed and the hole is open, blood should release from the fingernail (If not, repeat the procedure).
- Clean the area and keep your injured finger clean and dry for 2 days.
- This procedure can be repeated if blood continues to build up under the nail as the hole closes and pressure and blood rebuilds.
- Do not drain an injured fingernail unless your doctor has instructed you to do so.
- Do not apply a splint to the finger without first consulting your doctor.
- Do not wrap an injured finger. This can lead to further damage as air and nutrients cannot get the affected area to help the healing process.
