What should you know about excessive itching on feet?

Dry, cracked skin can itch more after hot showers or frequent washing. Redness or scaling between the toes may occur with a fungal or yeast-related problem. Contact Dermatitis can follow exposure to footwear materials, detergents, creams, or adhesives. Atopic Dermatitis and Asteatotic Eczema can cause dryness and an itchy barrier. Psoriasis or Lichen Planus may produce persistent, defined or rough patches. Scabies often causes intense itch and may affect household contacts, while Hives produce raised areas that come and go.

The same symptom can have different causes. Note whether there is scale, blisters, cracks, swelling, a rash elsewhere, or itch that is worse at night. This information helps guide an examination.

Wash with lukewarm water, use a fragrance-free cleanser, dry carefully between the toes, and apply a plain moisturiser to dry areas. Keep feet cool and dry, change damp socks, and avoid scratching. Do not share towels or footwear if a contagious rash is possible. Avoid applying steroid, antifungal, or antiseptic products repeatedly without checking that they fit the skin problem.

A clinician can distinguish eczema, psoriasis, contact irritation, yeast infection, scabies, and other causes by examining the distribution and surface of the rash.

Arrange an assessment if itching persists, keeps returning, spreads, disrupts sleep, or causes cracks and bleeding. Seek prompt care for rapidly spreading redness, warmth, swelling, pus, fever, severe pain, or a rash with facial swelling or breathing difficulty. People with diabetes, poor circulation, or reduced immunity should seek advice sooner when the skin breaks.

What does the location and surface of the rash suggest? Could footwear, a product, eczema, psoriasis, infection, or scabies be involved? Which treatment should I use, and for how long? How can I prevent recurrence or protect household contacts?
