What Is a Toenail Fungal Infection?
A toenail fungal infection is a common condition that affects the nail and the skin underneath it. It happens when tiny fungal organisms get into the nail, usually through small cracks or damage that you may not even notice.
You might first see a small patch of discolouration, often yellow, white, or slightly brown. Over time, the nail can become thicker, more brittle, and harder to cut. In some cases, it may start to lift away from the skin underneath.
Although it can begin as a mild cosmetic concern, a fungal nail infection does not usually clear up on its own. Without treatment, it can gradually worsen and become uncomfortable, particularly in shoes.
If you’re noticing thickened, discoloured, or difficult-to-cut nails, it’s worth having them assessed. Early intervention makes treatment far more straightforward.
