What should you know about care for thick toenails?

A thick nail may become yellow, white, brittle, ridged or difficult to cut. Nail Fungus is one possible cause, while Nail Psoriasis, repeated pressure, an old injury and changes in nail growth can look similar. A clinician may inspect the nail and take a clipping or scraping before recommending treatment.

A single altered nail after trauma is different from several nails changing gradually. The surrounding skin, pain level and pattern of growth help guide the assessment.

Wash and dry your feet carefully, especially between the toes. Trim nails after bathing when they are softer, cutting straight across and avoiding deep corners. Use clean tools, do not share them, and smooth sharp edges with a file. Choose shoes with enough toe room and change damp socks.

Do not force a thick nail to bend or tear it away. If testing confirms fungal infection, a clinician may discuss Oral Antifungal Treatment or Laser Treatment For Nail Fungus; the choice depends on the organism, nail involvement, health history and medicines.

Book an assessment if the nail keeps thickening, becomes painful, separates, or affects walking. Seek prompt care for redness, warmth, drainage, swelling, a dark streak that is new or changing, or a wound that does not heal. People with diabetes or reduced sensation should arrange foot problems early.

Ask whether the nail needs testing, how to trim it safely, whether other nails or skin are involved, which treatment matches the cause, and how to prevent pressure or reinfection.
