Avoid medical treatment with this family medicine secret.

Stubbed your toe, but want to wear your new sandals tomorrow? Maybe you’re going for a pedicure and don’t want to scare the beautician, or the blood underneath your nail is just causing a lot of painful pressure. Whatever your reasons, keep reading for how to make sure that bloody liquid drains out from under your nail bed, using only a humble paper clip.

If you have a blood blister under your nail (or subungual hematoma, if you prefer), you may be wondering what you can do to relieve the pain and get rid of the blister. While it is important to seek medical treatment if you have a severe injury or are in a lot of pain, there are some steps you can take at home to drain the blood and promote healing. Here is a guide on how to drain blood from under a nail:

Clean the area

Before attempting to drain the clear or bloody liquid, make sure to clean the area thoroughly. Wash your hands with soap and warm water, and use a disinfectant to clean the nail and surrounding skin. This will help to reduce the risk of infection and ensure that you are working in a clean environment.

Sterilize an ordinary paper clip

Next, you will need to sterilize a paper clip, needle or pin using a flame or rubbing alcohol. This is important to prevent infection and ensure that you are using a clean instrument.

Create a small opening

Gently press the tip of the sterilized needle or pin against the blister until you feel a small amount of resistance. Then, slowly push the needle through the blister to create a small opening. Be careful not to push too hard, as this can cause further injury or damage to the nail surface.

Gently squeeze the blister

Once you have created an opening, gently squeeze the blister to release the blood. If the blood does not drain easily, you can try gently massaging the area to help it along. Be sure to keep the area clean and avoid contaminating the wound with dirt or bacteria.

Apply a bandage or dressing

To protect the wound and promote healing, you can apply a bandage or dressing to the affected area. This will help to keep the area clean and prevent further injury.


It’s easy to drain subungual hematomas (or bleeding under the nail, to you and me) at home for quick and easy pain relief. Just remember, if you’re experiencing severe throbbing pain, have a large or deep wound, or have any other concerns, it is important to seek medical attention. A healthcare professional can provide you with further treatment and advice on how to care for the wound and prevent infection.
