Explainer | What to do if running is causing ingrown toe nails – symptoms, treatment and cure
- Ingrown toe nails are a common problem for runners, and can be very painful if left untreated
- There are a few simple remedies to prevent them returning and stopping your training again

An ingrown toe nail is when the nail is growing in the wrong direction – it grows or curls down into the skin, rather than parallel to the toe.
It is a common condition among runners, and can prevent them from training or taking part in races if it is severe or left untreated, and it can lead to infections.
Symptoms
There are a few signs that you might have an ingrown toe nail. If there is a sharp pain around the edges of your toe nail, it could be caused by the nail pressing against your skin.

If you apply light pressure with your fingers to the nail or effected area, the pain might increased. Putting weight on your toes may also increase this pain.
If the toe is red, hot or there is pus, it may be a sign that you have an ingrown toe nail and that it has become infected.
In extreme cases, the issue might be visible – such as the toe nail curled back on itself, digging into the skin.
Treatment
If the pain is severe, or the toe looks badly infected, seek medical advice. A podiatrist or your local GP are both suitable places to visit.
