Ingrown Toenail
An ingrown toenail, medically known as onychocryptosis, occurs when the edge of a toenail grows into the soft tissue around the nail, causing pain, inflammation, and sometimes infection. This typically happens on the big toe but can occur on any toe.

What are the symptoms of an ingrown toenail?
Ingrown toenails are often easy to identify because of the marked swelling at one or more sides of the nail combined with significant pain for those affected. Common symptoms include:
-
Redness
-
Tenderness
-
Swelling/inflammation
-
Mild to severe pain on touch
-
Occasional bleeding at the pierced site
-
Yellow/clear/green discharge if an infection is present
In severe cases, it will become difficult to wear shoes or have anything touching the toe, even something as light as a sheet in bed.

What causes ingrown toenails?
There is no single cause for ingrown toenails, but numerous factors that can encourage their development. The first of these is an improper nail cutting technique. Nails should be cut in a straight, clean line with no fraying or split edges.
Another common culprit is pulling or picking at the nails. Pulling the top of the nail off instead of cutting them in a straight line with a tool can leave a spicule at the edge of the nail where it is ripped off. Often, this spicule is deep down the side of the nail where it is not visible or felt - until it starts growing and pierces the skin.
Tight footwear is another common cause as it creates pressure on the sides of the toes that can push the nail into the surrounding skin. The shape of the nail can also play a role, especially where the nail is particularly involuted or curved. The shape of the nail, unless acquired from injury, is often linked to uncontrollable genetic factors that dictate the features and shape of the nail.

Caring for ingrown toenails at home
As mentioned, cutting your toenails in a straight line using nail tools is a good way to help reduce the risk of developing an ingrown toenail, alongside avoiding tight footwear and not ‘pulling’ at the nail.
If an ingrown toenail does develop, we recommend that you see your Podiatrist immediately before the nail grows deeper into the skin or an infection develops. To help manage your symptoms temporarily and reduce the risk of infection, you can soak your foot in warm water with epsom salts, dry it well, and apply an antiseptic to the ingrown toenail site.
If you have certain conditions like diabetes, nerve damage or poor circulation, it is essential that you see your Podiatrist immediately because of the increased risk of developing an infection.

How a Podiatrist can help
Ingrown toenails can be managed as a one-off treatment, or can be corrected permanently. For a one-off treatment for first-time ingrown toenails, your Podiatrist will remove the offending nail edge or spicule using specialised nail tools. Removing the nail spicule means that the pierced skin is able to heal and the inflammation, and hence pain, will be able to settle.
If you have a history of developing ingrown toenails then you may wish to permanently correct the problem. The procedure for the permanent correction is called a Partial Nail Avulsion (PNA). It involves removing a small section of the offending nail edge and applying a chemical to destroy the nail growing cells. The result is a clean, straight nail edge that is only marginally shorter than your standard nail and is often barely noticeable after it has healed. You will be able to discuss the best treatment options and outcomes with your Podiatrist.
