Introduction
Red, itchy rashes on the feet may be caused by factors such as athlete's foot, fungal infection, or contact dermatitis. Treatment generally depends on the underlying cause. It is also important to keep the feet clean and dry, avoid allergens and irritants, wear breathable shoes and socks, and maintain good foot hygiene, all of which can help relieve symptoms.

In general, red rashes on the feet accompanied by itching may be caused by factors such as beriberi, tinea pedis (athlete's foot), or contact dermatitis. Different treatments should be selected based on the specific cause. Detailed analysis is as follows:

1. Beriberi

Beriberi is a condition caused by vitamin B deficiency, with symptoms including redness, swelling, pain, and itching of the feet. Treatment may include topical application of ketoconazole cream or terbinafine cream, as directed by a physician.

2. Tinea Pedis (Athlete's Foot)

Tinea pedis is a fungal skin infection characterized by symptoms such as redness, swelling, pain, itching, and blister formation on the feet. Under medical guidance, treatments may include clotrimazole cream or mometasone furoate cream.

3. Contact Dermatitis

Contact dermatitis is a skin condition triggered by exposure to allergens, presenting symptoms such as redness, swelling, pain, itching, and rash on the feet. Antiallergic and antipruritic effects can be enhanced by taking medications such as fexofenadine hydrochloride tablets or desloratadine capsules, as prescribed by a doctor.

In addition, urticaria could also be a possible cause. If red, itchy rashes appear on the feet, prompt medical consultation is recommended, and the doctor will provide appropriate treatment based on the condition. Meanwhile, it is important to maintain clean and dry feet, avoid exposure to allergens and irritants, wear breathable shoes and socks, and practice good foot hygiene, all of which help alleviate symptoms.
