Left foot itching in women

Peeling or cracking between the toes, especially after sweaty footwear, can fit a fungal infection. Dry, tight or flaky skin on the sole may reflect asteatotic eczema, while itchy inflamed patches can occur with atopic dermatitis or psoriasis. A rash that started after shoes, socks, polish or a product may be contact dermatitis. Small bumps or widespread itch can occur with hives, scabies or other causes. The fact that only the left foot itches does not establish a diagnosis. Note whether the problem affects the toes, sole, top of the foot or ankle.

Wash gently, dry carefully between the toes and change damp socks. Use breathable footwear and avoid sharing towels, shoes or nail tools while a contagious rash is possible. Stop any newly introduced foot product and use a plain moisturiser on dry, unbroken skin, keeping cream out of toe webs if they are moist. Avoid scratching and do not use a steroid, antifungal or combination cream at random, because the wrong treatment can obscure the pattern. A pharmacist or clinician can match treatment to the appearance.

Arrange an appointment if the itch lasts, spreads, keeps returning, causes cracks or affects sleep. Seek prompt care for increasing warmth, swelling, pain, pus, red streaks or fever, especially with diabetes or reduced immunity. Urgent assessment is needed for sudden facial swelling, breathing trouble or a rapidly spreading allergic rash. A clinician may examine the skin and nails and check for infection before recommending treatment.

Does the pattern look fungal, eczematous, allergic or something else? Should the nails or the other foot be examined? Which product is safe for my skin and medicines? How can I prevent recurrence in footwear?
