itchy feet
Introduction
Introduction Itchy foot is a common symptom of athlete's foot. It is caused by fungal infection. Its skin damage often occurs on one side (ie, one foot), and it only affects the contralateral side after several weeks or months. Blisters mainly appear on the toes and toes, most commonly between the three to four toes, and the soles of the feet can also appear as deep blister, which can gradually fuse into bullae. The skin lesion of the ankle has a characteristic that the boundary is clear and can gradually expand outward. Due to the development of the disease or scratching, there may be erosion, exudation, or even bacterial infection, pustules and the like.
Cause
Cause
1. There is no sebaceous gland in the soles and toes of the human body, which lacks the fatty acids that inhibit the filamentous fungus of the skin. The physiological defense function is poor, and the sweat glands of these parts are very rich, sweating is more, and the air circulation is poor, local moist. Warm, conducive to the growth of filamentous fungi. In addition, the stratum corneum of the foot is thicker, and the keratin in the stratum corneum is a rich nutrient of the fungus, which is beneficial to the growth of fungi.
2, the skin of the foot is traumatized, destroying the defense function of the skin, and is also one of the factors inducing athlete's foot.
3, the abuse of antibiotics, long-term use of corticosteroids and immunosuppressive agents, so that the normal flora of the skin disorders, will also increase the susceptibility of athlete's foot.
4, the incidence of athlete's foot is also related to living habits. Some people do not pay attention to the condition of foot cleaning and footwear, providing a good breeding ground for fungi.
