What does it mean if pus is coming from under your toenail?

Pus coming from under your toenail is a sign of an underlying infection. It's important to seek medical attention if you notice pus or other signs of infection, such as redness, swelling, warmth, or pain.

Here are some possible causes of pus under the toenail:

* Fungal infection: This is the most common cause of pus under the toenail. Fungal infections, also known as onychomycosis, can cause the nail to become thickened, discoloured, and brittle. They can also lead to infection of the skin under the nail.

* Bacterial infection: Bacterial infections of the toenail can also cause pus to form. These infections are often caused by bacteria that enter through a cut or other injury to the nail.

* Trauma: Trauma to the toenail, such as stubbing your toe, can also cause pus to form. This is because trauma can damage the nail and allow bacteria to enter.

* Underlying medical conditions: Some underlying medical conditions, such as diabetes, can increase your risk of developing an infection of the toenail.

Treatment for pus under the toenail typically involves antibiotics or antifungal medications. In some cases, the infected nail may need to be removed.

To prevent pus under the toenail, it's important to keep your feet clean and dry. You should also avoid walking barefoot in public areas and wear shoes that fit well. If you have a cut or other injury to your toenail, be sure to clean it and apply a bandage to keep it protected.
