What should you know about sore thick toenail?

A nail can thicken when repeated shoe pressure or an old injury alters its growth. Nail Fungus often changes colour or texture and may cause crumbly material beneath the nail. Nail Psoriasis can produce pits, separation or discolouration, sometimes alongside skin or joint symptoms. Pain may come from the thick nail pressing on footwear or surrounding skin rather than from the nail plate itself. Examination helps separate these causes because treatments are not interchangeable.

Wear shoes with enough room at the toes and keep the nail clean and dry. Trim straight across only when the nail is manageable; do not dig into the corners or force a painful nail thinner. Avoid sharing nail tools, and have instruments cleaned between uses. If fungus is suspected, a clinician may discuss Oral Antifungal Treatment or Laser Treatment For Nail Fungus after confirming the diagnosis. Do not treat psoriasis as fungus without advice.

Book an assessment when pain keeps returning, the nail lifts, drainage or swelling develops, or the change affects one nail without a clear injury. Seek prompt care for spreading redness, severe tenderness or fever. People with diabetes, poor circulation or reduced sensation should arrange advice early for any painful nail problem.

Does the nail look more consistent with pressure, Nail Fungus, Nail Psoriasis or injury? Is testing needed before treatment? Which trimming method is safest for this nail? Would Oral Antifungal Treatment or Laser Treatment For Nail Fungus be appropriate, and what monitoring would be needed?
