What causes red, itchy bumps on the feet?
Disease description:
Recently, many red bumps have appeared on my feet, and they are very itchy. Why do red bumps appear on the feet and cause itching?

Red, itchy bumps on the feet may be caused by various factors, including viral infections, fungal infections, bacterial infections, parasitic infections, and allergies. Specifically, they could be due to viral skin diseases such as erythema infectiosum (fifth disease) or hand, foot, and mouth disease, or fungal infections such as athlete's foot. Bacterial and parasitic infections, such as insect bite dermatitis, can also lead to similar symptoms. In addition, allergic reactions—for example, to new socks or new shoes—may also cause red bumps and itching on the feet.
To alleviate these symptoms, it is recommended to first keep the feet clean and dry, and avoid scratching to prevent worsening of symptoms or secondary infection. Seek timely medical evaluation to determine the exact cause and follow the doctor's instructions for targeted treatment. In daily life, choose breathable shoes and socks, and regularly wash and disinfect them to reduce the occurrence of foot skin problems.
