How to Care the Blood Blister Under My Nail?

The treatment for a blood blister is fairly simple to do at home with the right tools. Simply clean the area and make a small hole in the nail to allow the blood to drain.

Tools
Alcohol pad
18-gauge needle
Peroxide
If you do not have the tools, then stop by your local health care provider, who can drain it for you in a quick visit.

If there is no pain, then you may leave the blood blister alone as they frequently clear up on their own. However, get it checked out at the first sign of pain or discomfort—you need to rule out the possibility of an infection.

Step 1: Clean the Needle and the Toe
Open the alcohol pad and use it to clean the needle, then the toe.

Step 2: Drill a Hole
Place the point of the needle on the center of the nail (or the center of the blood blister). Drill through the nail by rotating the needle left and right. Note: This is a painless procedure because the nail does not have any nerves. Do not apply a lot of pressure; the needle will drill through gradually.

Step 3: Let Out the Blood
When you see blood, wipe it away with the alcohol pad. Drill a little more after you first see blood to make sure that the hole is big enough to allow the rest of the blood to come out.

Step 4: Keep Blood from Clotting
In order to allow the continued release of blood over the next day or so, do not allow blood to clot in the hole. If it does so, dab peroxide on it to clear the hole once more.
