When to worry about itchy feet with contact dermatitis

Contact dermatitis is skin inflammation after contact with an irritant or an allergen. On the feet, possible triggers include footwear materials, adhesives, dyes, rubber, detergents, or topical products. Itching may accompany redness, dryness, scaling, burning, or small blisters where contact occurred. A fungal infection can look similar, especially between the toes, so the pattern and trigger history matter.

Stop using a suspected new product or pair of shoes and keep a note of when symptoms appear. Rinse irritant residue gently, pat dry, use a plain moisturiser, and choose clean breathable socks and shoes. Avoid scratching and avoid applying multiple medicated creams at once. A clinician can help identify the trigger and recommend treatment that fits the location and severity.

Arrange an appointment when the rash persists after avoiding the suspected trigger, keeps returning, spreads beyond contact areas, or interferes with sleep or walking. Seek prompt care for increasing pain, warmth, swelling, pus, red streaks, fever, or extensive blistering. Get urgent help for facial swelling, wheezing, throat tightness, or trouble breathing after exposure.

Ask whether the pattern fits contact dermatitis or fungal disease, which ingredients or materials to avoid, whether patch testing could help, and how to protect cracked skin while it heals.
