What should you know about nail thickening and discoloration?

A thick nail with crumbly material, lifting, or gradual colour change can occur with Nail Fungus. Nail Psoriasis may produce pits, ridges, thickening, or separation and can affect several nails. Pressure and trauma often relate to a particular finger or toe, especially where footwear rubs. Polish or repeated contact with pigments can stain the surface. These clues overlap, so a clinician may need to examine or sample the nail.

Keep nails short and dry, use clean tools, and avoid scraping beneath the plate. Choose footwear that does not press on the toes and protect hands during wet work. Do not cover an unexplained change with layers of polish. If fungus is suspected, diagnosis should guide treatment; options may include Oral Antifungal Treatment or Laser Treatment For Nail Fungus, depending on the findings and your medical history.

Book an assessment for persistent change, multiple affected nails, pain, lifting, or difficulty trimming. Seek prompt care for pus, warmth, swelling, fever, bleeding, or a dark streak that changes or extends onto nearby skin. People with diabetes, circulation problems, or reduced immunity should not delay evaluation of a new nail problem.

Ask which features point toward Nail Fungus or Nail Psoriasis, whether testing is needed, how to manage pressure or injury, and which treatment is appropriate for the number and location of affected nails.
