If you’ve had many fungal toenail infections in the past, you’ll know that while they aren’t particularly serious, they can be unpleasant to look at and difficult to treat.
But you’re not alone in having fungal nail infections - they’re common, and you’re more likely to get a fungal infection in your toenails than fingernails.
Typically, an infected nail turns yellow or green in colour before it thickens and becomes brittle. And if left untreated, you may also notice pain and swelling in the skin around the nail.
If you’ve had a fungal toenail infection in the past, here are a few steps you can take to prevent it from returning in the future.

You should see a doctor if you’re worried about the infection, it has spread to other nails or non-prescription treatments haven’t worked.
