The cause of itchy and swollen feet may be contact dermatitis, frostbite, athlete’s foot and other diseases.
1. Contact dermatitis: the skin on the feet comes into contact with detergents and industrial chemicals, such as phosphorus-containing laundry detergents, which irritate the skin tissues and cause pimples, blisters, itching and other symptoms, and prolonged scratching of the skin may lead to itchy and swollen feet.
2. Frostbite: also known as cold injury, is the low temperature caused by the skin or subcutaneous soft tissue damage, due to skin vasoconstriction, poor blood circulation, may lead to itchy and swollen feet.
3. Tinea pedis: walking barefoot in public bathrooms, gyms, swimming pools and other public areas, sharing towels, or mistakenly wearing shoes and socks of patients with tinea pedis, direct or indirect contact, will be infected with dermatophytes, ultimately causing tinea pedis, resulting in itchy and swollen feet.
If your feet are itchy and swollen, there may be other conditions, so you can go to the hospital to complete the relevant examinations to clarify the situation and take corresponding measures.
