What should you know about Nd:YAG laser for onychomycosis?

Onychomycosis is a fungal infection affecting the nail plate or tissue beneath it. Thick, yellow, white, or crumbly nails can have other causes, including injury or inflammatory skin disease, so discoloured nails should be assessed rather than assumed to be fungal.

Nd:YAG laser delivers energy to the affected nail area. Clinics may offer it alone or alongside antifungal medicine, depending on the examination and the number of nails involved. A nail grows slowly, so visible improvement depends on healthy nail replacing damaged nail.

Have a clinician examine the nail and check for athlete’s foot or infection in nearby skin. Mention diabetes, reduced circulation, immune problems, liver disease, pregnancy, current medicines, and previous antifungal treatment. These details can change which options are appropriate.

Keep feet clean and dry, change socks regularly, and avoid sharing nail tools. Follow the chosen plan for the full recommended course. Laser may not address fungus elsewhere on the foot, and untreated surrounding infection can contribute to repeated nail problems.

Arrange medical review for a painful, swollen, draining, or suddenly dark nail, especially after an injury. Seek prompt care if redness spreads around the toe, you develop fever, or walking becomes difficult. People with diabetes or poor circulation should seek advice early for any foot wound or infection.

Ask how the diagnosis was made, whether a nail sample is needed, why laser is being suggested, and whether oral or topical antifungal treatment is more suitable. Ask how nearby athlete’s foot will be treated, what improvement to expect as the nail grows, and how recurrence will be managed.
