What should you know about left toe itching?

A tight shoe, rubbing seam, sweat, or a new product may irritate one toe. Dry scaling may occur with asteatotic eczema or atopic dermatitis, while redness after an exposure may fit contact dermatitis. Peeling or maceration around the toe can occur with a skin yeast infection.

A sharply defined thick patch may be psoriasis or lichen planus. Itch that spreads, is worse at night, or affects close contacts warrants consideration of scabies. Brief raised welts are more consistent with hives than with a fixed toe rash.

Check the toe for a blister, splinter, crack, scale, discharge, or pressure mark. Keep it clean and dry, change out of damp socks, choose roomier footwear, and use a plain moisturiser on dry intact skin. Avoid scratching and stop a new product until the skin settles.

Do not share towels or footwear if there is peeling or a suspected infection. A clinician can choose treatment after examining the toe, nail, and nearby skin.

Seek prompt assessment if redness spreads, the toe becomes hot or very swollen, pus appears, pain is strong, fever develops, or walking becomes difficult. A rapidly worsening wound needs timely attention.

Arrange a review for persistent itch, recurrent cracking, nail changes, night-time itch, or symptoms in household contacts. Emergency help is needed for breathing trouble or facial swelling with a widespread rash.

Could footwear or contact exposure explain this pattern? Do you see signs of eczema, yeast infection, or another condition? What should I use on cracked skin, and how should I protect the other toes?
