What should you know about thickening of toe nails?

A toenail can become dense, yellow or white, ridged, crumbly, or difficult to cut. Nail Fungus commonly changes the nail plate and may cause debris beneath it, but similar changes can follow repeated pressure from footwear or an old injury. Nail Psoriasis may cause pits, lifting, colour change, or scaling around the nail. Several causes can coexist, and a nail sample may be needed because visual inspection cannot always distinguish them. Tell the clinician whether one nail or several are changing and how long the process has been present.

Choose shoes with enough room around the toes, keep feet dry, and change socks when damp. Trim nails straight across without digging into the corners, and use separate clean tools for affected nails. Avoid sharing clippers or applying harsh chemicals. If testing confirms fungus, a clinician may discuss Oral Antifungal Treatment or Laser Treatment For Nail Fungus, depending on nail involvement, medicines, and medical history. Treating the cause is more useful than repeatedly thinning the surface.

Make an appointment if a nail remains thick, becomes painful in shoes, lifts, or changes alongside other nails or skin. Seek prompt care for pus, spreading redness, warmth, swelling, or rapidly worsening pain. A new dark mark, bleeding, or a stripe that changes should be examined promptly. If you have diabetes, numbness, or circulation problems, have nail and skin injuries checked early and avoid self-treatment that can break the skin.

Could this be Nail Fungus, Nail Psoriasis, pressure, or an injury? Should a sample be tested? Which treatment is appropriate for my health history, and how can I prevent shoe pressure while the nail grows?
