What should you know about nail thick and yellow?

Fungal nail infection often changes the nail's colour and texture and may create crumbly material underneath. Nail psoriasis can cause thickening, ridges, pits, or lifting and may occur with psoriasis elsewhere. Repeated pressure from footwear or an old injury can also make a nail grow irregularly. A yellow colour can come from cosmetic staining or other conditions, so the colour alone does not establish the diagnosis.

Keep the nail trimmed without cutting into the surrounding skin, dry feet carefully after washing, and choose shoes with enough room at the toes. Do not share clippers or dig beneath the nail. A clinician may inspect the nail and take a sample before treatment. Oral Antifungal Treatment is one possible option when fungus is confirmed, but treatment choice depends on the nail and your health.

Arrange an appointment if the nail remains thick or yellow, several nails change, walking becomes uncomfortable, or the nail lifts. Seek prompt care for spreading redness, warmth, pus, severe pain, fever, or a dark streak that is widening or reaching the surrounding skin. Earlier review is wise with diabetes, poor circulation, or reduced immunity.

Ask whether the findings fit Nail Fungus, Nail Psoriasis, staining, or injury; whether a sample is required; and what treatment and nail-care plan is safest for you.
