Pus flowing from the toe nail is usually considered to be nail fungus, which is caused by bacterial infection and has symptoms such as redness, swelling, heat and pain. The cause of this symptom is due to the nail groove stabbing, often wearing shoes that do not fit the foot, and the toe being squeezed for a long time. If the pus is serious, it is recommended to cut and drain the nail groove; if the pus is in the nail bed, it is recommended to extract the nail. It is important to take oral antibiotics to prevent infection, and to wear more breathable shoes, keep the feet clean and dry, change socks and shoes regularly, dry them more often, and disinfect shoes when necessary. Diet should be light, eat more vegetables and fruits, avoid spicy and stimulating as well as spicy food such as fish, shrimp, crab, etc. This disease should not be treated blindly on its own, often delaying and aggravating the condition.
