What should I do if I get itchy red rashes on my feet?

When red, itchy rashes appear on the feet, targeted treatment should be carried out according to the specific cause. Possible causes include insect bites, eczema, urticaria, tinea pedis (athlete's foot), and dyshidrotic eczema. Management methods include: 1. **Insect bites**: Itch relief may be obtained through the use of calamine lotion, paeonol ointment, or essential oils such as wind oil. The rash typically resolves naturally. 2. **Eczema**: Keep the feet clean and dry, avoid scratching, rinse with calamine lotion, and apply topical corticosteroid creams such as mometasone furoate ointment for treatment. 3. **Urticaria**: When caused by allergies, oral antiallergic medications such as loratadine tablets or ephedrine hydrochloride tablets may be taken. Re-exposure to the allergen should also be avoided. 4. **Tinea pedis**: Apply topical antifungal medications such as compound benzoic acid tincture or terbinafine hydrochloride ointment. Personal hygiene should be maintained to prevent cross-infection. 5. **Dyshidrotic eczema**: Treat with halcinonide ointment or hydrocortisone butyrate ointment, while keeping the feet well-ventilated and clean, and avoiding excessive sweating.
