What should you know about proximal white subungual onychomycosis?

The white change starts near the cuticle and can move outward as the nail grows. The nail may become opaque, rough, thickened, brittle, or partly separated from the nail bed. Athlete's Foot can coexist because fungi may spread between foot skin and nails, although a pale nail is not enough to confirm infection.

Several nail conditions can resemble fungal disease. A clinician may inspect the nail and take clippings or scrapings before choosing treatment, especially when the appearance is unusual or only one nail is involved.

Keep the nail short and dry, change damp socks, use breathable footwear, and avoid sharing nail tools. Treating Athlete's Foot at the same time may reduce a source of reinfection. Do not scrape beneath the nail or rely on cosmetic cover while the diagnosis is uncertain.

Depending on the extent and location, treatment may involve Topical Antifungal Treatment or Oral Antifungal Treatment. Laser Treatment For Nail Fungus and Nail Surgery may be discussed in selected situations, but neither should be chosen without an assessment of the nail and surrounding skin.

Book an assessment for new white change near the nail base, spreading discoloration, pain, swelling, or nail separation. Seek prompt care if pus, marked tenderness, redness extending into nearby skin, or fever develops. A dark streak or rapidly changing pigment also needs timely examination.

Ask whether testing is needed, whether the pattern fits Nail Fungus or another nail disorder, how long treatment may take, whether other nails or foot skin should be checked, and how to reduce spread between nails and footwear.
