What should you know about LED light for nail fungus?

A fungal nail infection can thicken, crumble, or change the colour of a nail, but injury, psoriasis, bacterial infection, and other problems can look similar. A sample or clinical examination may be needed before treatment. Read about [Nail Fungus](/conditions/nail-fungus/) and [Discoloured Nails](/symptoms/nail-discoloration/).

An LED device exposes the nail or surrounding area to light. The proposed aim may be to affect organisms or support local care, but light does not remove infected nail or replace an antifungal medicine when one is indicated. Nail growth is gradual, so a healthy-looking section must grow from the base before improvement is visible.

Have the nail assessed and mention diabetes, reduced circulation, immune problems, pregnancy, and all medicines. Keep feet clean and dry, change damp socks, avoid sharing nail tools, and treat coexisting [Athlete's Foot](/conditions/athletes-foot/) if present. Do not scrape deeply or cover a suspected infection with cosmetic products.

Depending on the number of nails, severity, and health history, a clinician may discuss [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/), [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/), or [Laser Treatment For Nail Fungus](/treatments/laser-and-energy/laser-nail-fungus-treatment/). Nail surgery is reserved for selected situations, not routine LED use.

Arrange prompt review if the skin around the nail becomes red, hot, swollen, or draining, or if pain makes walking difficult. Seek earlier advice for a rapidly changing dark streak, bleeding, or a single nail that changes without an obvious injury. Fever or spreading redness needs urgent medical attention.

How will we confirm fungus rather than another nail condition? Is LED appropriate for my result? Would a topical or oral medicine be safer or more effective for me? How should I protect other nails and monitor regrowth?
