There are small black spots on my feet from being pierced by nails

I accidentally got pricked in the foot by a nail. Although I was wearing shoes, the nail was too long and too sharp, and it still pierced into the skin. Although it was not deep, it was very painful. After it slowly healed, I found that a small black spot was left. It is very common to have small black spots on your feet after being pricked by nails. If there are no discomfort symptoms, it may be because some dirt from the nail has entered the surface of the skin. Of course, it would be troublesome if the wound became infected.

1. What should I do if a nail pricks my foot and there is a black spot at the puncture site after it heals?

This is not a big problem. Maybe some dirt was brought to the cortex at that time. Now it is covered by scars, which means it has been controlled. As long as there is no redness, swelling, or pain, no treatment is required. If there is redness, swelling, pain, or other discomfort, you can go to the hospital outpatient clinic to choose surgical treatment. The details can be determined after observing for a period of time.

2. After the foot is pierced by a nail, is it serious if the wound turns black?

The patient may have a local infection. It is recommended that the patient receive infusion treatment and disinfect the local area with alcohol or iodine. The clinical manifestations mentioned by the patient have no direct relationship with tetanus, but the patient should still receive an injection of tetanus antitoxin to prevent tetanus infection.

3. What to do if you are pierced by a nail

1. If you are accidentally pricked by a nail and the wound is bleeding, try to squeeze out some of the dirty blood and check whether the nail is rusty. If there is rust, you cannot handle it yourself and need to go to the nearest hospital or clinic for treatment.

2. If there is no rust on the nail, the wound is not deep, and the area around the wound is relatively clean, wash your hands first, squeeze out the dirty blood again, suck out the dirty blood from the wound with your mouth and spit it out, and repeat 2 to 3 times.

3. If you have medicines for treating wounds, you can use alcohol or hydrogen peroxide to disinfect the wound, and cover the wound with a Band-Aid or clean gauze to protect it. If the injury is serious and conditions permit, you can apply anti-inflammatory ointment on the wound. If not, you can use erythromycin eye ointment instead.

4. Change the Band-Aid or gauze every day. Repeat the disinfection and application process when you were injured before changing it. Observe the recovery of the wound while changing it. If the redness and swelling of the wound are slowly subsiding, you can stop bandaging the wound after three days and let the wound heal slowly.
