This disease is caused by dermatophytes (fungi or molds). Sweating, damp feet or airtight shoes and socks can induce this disease. Skin fungi often spread through polluted bathrooms, swimming pool floors, bath towels, public slippers and footbath.
Usually athlete's foot is divided into three types: erosive athlete's foot, blister athlete's foot and keratotic athlete's foot.
1. erosive type: it occurs between the third and fourth toes and between the fourth and fifth toes. When the toes first get wet, they are soaked in white or small blisters. When drying and peeling, the desquamation place is wet, red and itchy, which is easy to cause secondary infection.
2. blister type: it occurs at the edge of the foot. At first, there are small blisters with full wall thickness, and some can be merged into large blisters. The blister liquid is transparent and there is no blush around it. Self-conscious itching often leads to erysipelas and lymphangitis due to secondary infection after scratching.
3. Keratinization type: occurs in the heel. The main manifestations are thick and dry skin, keratinization, desquamation, itching and easy chapping. This type has no blister and suppuration, and the course of disease is slow, and it will not heal for many years.
traditional Chinese medicine
Athlete's foot, also called foot weakness. The main symptoms of this disease are numbness, pain and weakness in the feet and tibia. This disease was discussed in detail in Sui Fang's Theory of Etiology and Staging of Various Diseases. Clinically, according to its symptoms, it is mainly divided into dry beriberi, wet beriberi and heart-pounding beriberi.
The disease is mainly caused by Shui Han's disease, damp heat invading the lower limbs and overflowing the flesh and blood veins; Or improper diet, damage to the spleen and stomach, damp heat flowing into the foot and tibia; Or due to physical weakness due to illness, loss of qi and blood, loss of self-restraint of meridians and veins. If the damp toxin attacks, the mind will be palpitation and fidgety when disturbed, and the lungs and stomach will hold their breath and feel sick when they run along the meridian.
Distinguish the symptoms of a disease
At the beginning of the disease, I only feel weak feet, gradually aching and numb, and then the lower limbs are soft and thin, or swollen. Therefore, it can be divided into dry and wet categories:
Wet beriberi tends to be empirical, with swollen feet and shin, even swollen knees, slow pulse and white greasy tongue coating;
Dry beriberi tends to deficiency syndrome, which is characterized by thinner and thinner skin on feet and tibia, cold and numbness, weak body and mind, or constipation, pale tongue with red fur, and thin or numbered pulse. If you see symptoms of qi deficiency, dyspnea, palpitation, fever and unconsciousness, it is called "beriberi rushing to the heart", which is really a dangerous situation.
