What should you know about an itchy rash on the feet?

Scaling, peeling, or cracking between the toes can occur with Ringworm, especially when footwear keeps the area warm and damp. Blisters or intense itch on the soles may occur with eczema, while thick, sharply defined scale can occur with Psoriasis. New shoes, socks, adhesives, dyes, or foot products may trigger Contact Dermatitis. Sweat and friction can contribute to Heat Rash or Intertrigo in adjoining moist areas. Atopic Dermatitis may affect dry, irritated skin. Scabies is more likely to be considered when itch is widespread or close contacts are also affected.

Wash gently and dry carefully between the toes. Change damp socks, choose breathable footwear, and alternate shoes so they can dry fully. Avoid scratching, harsh antiseptics, and fragranced foot products. Do not share socks, towels, shoes, or nail tools if the rash is scaly or spreading. Keep a photo record and note whether the change began after new footwear, exercise, swimming, or a medicine. A pharmacist or clinician can help select treatment; avoid using multiple creams at once because this can obscure the appearance.

Seek urgent help for rapidly spreading redness, severe swelling, fever, severe pain, purple or black skin, or red streaking. Arrange prompt review for pus, open cracks that are worsening, inability to walk comfortably, or a foot that feels unusually hot. People with diabetes, poor circulation, reduced sensation, or a weakened immune system should seek advice early for new foot skin changes. Make an appointment if the rash persists, returns, involves the nails, or does not improve with appropriate basic care.

Ask: Does the distribution fit Ringworm, Contact Dermatitis, eczema, or Psoriasis? Should the skin or nail be tested? How can I keep footwear and socks dry? Which treatment is safe if the skin is cracked? Do my medical conditions change how quickly I should be seen?
