An ingrown toenail occurs when one or both of the sides of your toenail grow into the surrounding skin. This can cause pain, swelling and infection.
Key points about ingrown toenail
- This is a common problem that particularly affects teenagers and young adults.
- It usually affects your big toe but can also happen on other toes.
- Causes of an ingrown toenail include badly cut toenails, poorly fitted shoes, tight socks, fungal nail infections, foot injuries, sweaty feet or genetics.
- Symptoms include pain and redness at the nail edges of your affected toe.
- Treatment ranges from self-care measures to minor surgery to remove your whole nail or cut away part of your nail.
- You can prevent an ingrown toenail by cutting your nails correctly and not wearing poorly fitted shoes and socks.

What are the causes of an ingrown toenail?
An ingrown toenail can happen due to a number of causes.
- Badly cut toenails – cutting your toenails too short or into the corners can break the natural skin barrier. This increases the risk of infection and allows your skin to fold over the nail edge and your nail to grow into it.
- Increased pressure from tight shoes, socks or tights.
- Foot injuries – ingrown toenails can appear after injuring your toe.
- Sweaty feet.
- Fungal nail infections can cause a thickened or widened toenail.
- Genetics and natural toenail shape – toenails that are more curved or fan-shaped are more likely to press into the sides.
- Medicines such as isotretinoin.
What are the symptoms of an ingrown toenail?
Typical symptoms include:
- a red and painful edge of the toenail
- pain when wearing shoes due to pressure on your toe
- a raised area along the toenail edge from an overgrowth of skin.
If your ingrown toenail gets infected, your toe can become more swollen and the pain and redness can get worse, and sometimes blood or pus can come out from it.
How is an ingrown toenail diagnosed?
Your doctor will ask you questions about your symptoms and examine your toe to see if it is infected. Usually no tests are needed to diagnose an ingrown toenail.
How is an ingrown toenail treated?
Treatment of an ingrown toenail consists of self-care measures and a minor surgery.
Your GP will first recommend self-care measures to help relieve your symptoms, such as:
- soaking your foot in warm water 3 to 4 times a day for a few days – this will help soften the skin around your toe and stop your nail growing into it
- keeping your foot dry at other times
- wearing well-fitting and comfortable shoes
- taking pain relief medicines such as paracetamol or ibuprofen to relieve your pain – check with your GP or pharmacist whether you can take them
- not cutting or picking at your toenail – instead allow it to grow out so it is easier to cut it straight across.
If your symptoms don’t improve after self-care measures, or if your ingrown toenail is infected, your GP may prescribe antibiotics.
They may also perform a minor surgery to remove your whole nail or cut away part of your nail. They may also refer you to a podiatrist who can perform this minor surgery.
Your GP will discuss the best treatment options with you.
How can I prevent an ingrown toenail?

- Wear comfortable, well-fitting shoes or sandals.
- Avoid tight socks and change them every day.
