Blue light for nail fungus: what to know

Nail fungus can thicken, crumble, or discolour part of a nail and may spread between nails or to surrounding skin. Blue-light and laser systems aim energy at the affected nail, but the nail grows slowly and visible improvement depends on healthy nail replacing damaged nail. A single discoloured nail is not proof of fungal infection: trauma, psoriasis, pressure, and other problems can look similar.

A clinician may examine the nail and, when needed, test material before choosing treatment. Athlete's Foot can coexist with fungal nails, so itchy or scaling skin between the toes should be mentioned during assessment.

Keep feet clean and dry, change damp socks, wear breathable footwear, and avoid sharing nail tools. Do not cover a suspected infection with cosmetic nail products until it has been reviewed. Trim nails carefully and avoid cutting the surrounding skin.

Depending on the number of nails, thickness, health history, and test result, options may include Topical Antifungal Treatment, Oral Antifungal Treatment, or Laser Treatment For Nail Fungus. Nail Surgery is reserved for selected situations and does not remove the need to address infection when one is present.

Arrange medical advice for a nail that becomes painful, lifts, drains, or changes quickly. Seek prompt care if redness or swelling spreads around the nail, or if you have diabetes, poor circulation, reduced immunity, or a foot wound. A dark streak that is new or widening also needs assessment rather than light treatment.

How was fungus confirmed? How many nails are involved? Is a topical, oral, or light-based option appropriate for me? What monitoring is needed with tablets? How can I prevent reinfection from footwear or surrounding skin?
