Eczema on the feet may be due to the abundant sweat glands on the soles of the feet, which are easy to sweat. If you exercise for a long time and wear shoes and socks with poor permeability, it may lead to fungal infection on the feet, also known as beriberi. If the treatment is not timely after fungal infection, repeated scratching will trigger eczema like changes. Eczema caused by fungal infection should be treated with antifungal drugs in a timely manner. If the feet are exposed to some allergic substances, eczema may also occur on the feet. When eczema is too serious, it should be treated with anti allergic drugs, such as loratadine. Pay attention to foot care in daily life, keep it clean and dry, replace comfortable and breathable shoes and socks, and avoid long-term exercise.
