Itchy toes may be caused by fungal infections. Since the toe crevices are generally not easily ventilated and often sweat, they are prone to fungal infections. When these papules and herpes irritate the subcutaneous peripheral nerves of the skin, it may induce an itching sensation. Once it is itchy, some people may not be able to resist scratching, scratching if the skin breaks, there may be a secondary bacterial infection. So itchy toe seams need to be treated as early as possible and in time.
