What should you know about onychomycosis of toenails?

An affected toenail may become yellow, white, or brown, thicker than usual, crumbly at the edge, or separated from the nail bed. Fungal infection can occur alongside Athlete's Foot, so scaling or itching between the toes is worth mentioning. Similar changes can also come from injury, psoriasis, or other nail conditions; a clinician may examine the nail and, when needed, test clippings before choosing treatment.

Keep feet clean and dry, change damp socks, choose shoes with room for the toes, and avoid sharing nail tools. Trim the nail carefully rather than tearing it. Treatment depends on how much of the nail is involved and your general health. Options include Topical Antifungal Treatment, Oral Antifungal Treatment, or selected laser treatment; Nail Surgery may be considered when a nail is painful or difficult to treat.

Arrange a medical assessment if the nail is painful, lifting, spreading to other nails, or not improving with sensible foot care. Seek prompt care for redness, warmth, swelling, pus, rapidly increasing pain, or fever. People with diabetes, reduced circulation, nerve problems, or a weakened immune system should have new nail changes assessed early.

Ask whether the appearance needs a nail test, which treatment fits the affected area, how long to use it, and how to protect nearby skin and nails from reinfection.
