What should you know about toe nail fungus care?

Nail fungus can make a toenail thick, brittle, crumbly or yellow-white, and debris may collect beneath it. Similar changes can follow injury, psoriasis or other nail conditions, so colour alone does not confirm infection. Athlete’s foot may occur alongside fungal nails and can keep spreading organisms between skin and footwear. The affected nail must grow out gradually, so improvement is judged by healthy nail emerging from the base rather than an instant colour change.

Keep feet clean and dry, dry carefully between toes, change socks when damp and choose shoes that allow airflow. Trim nails straight across without digging into the corners, and do not share clippers or files. A clinician may prescribe topical antifungal treatment for suitable cases or oral antifungal treatment when infection is extensive or difficult to reach. Laser treatment or nail surgery may be discussed in selected situations. Treat coexisting athlete’s foot and follow the full plan even when the nail looks better.

Arrange an assessment for a new nail change, pain, lifting, repeated breakage or infection affecting several nails. Seek prompt care for redness, warmth, swelling, drainage or pain around the nail. People with diabetes, reduced circulation, nerve damage or immune suppression should obtain professional advice early and avoid self-removing the nail.

Ask whether a nail sample is needed, which treatment fits the number and depth of affected nails, how medicines interact with your health, and how to prevent spread through shoes and nail tools.
