Separation of the nail from the flesh can usually be healed with medication or through diet. 1. Drugs: Nail and flesh separation is usually caused by traumatic impact, nail malnutrition and other conditions, resulting in nail loss. Patients should go to the hospital in time to disinfect and bandage the wound, and use drugs such as Itraconazole and Clotrimazole ointment for antibacterial treatment under doctor’s instruction. 2. Diet: During the healing period, the patient’s diet should be nutritionally balanced, eat more calcium and vitamin-rich foods, such as carrots, eggs, fish, etc., which can replenish the body’s vitamins as well as missing nutrients, and avoid spicy and stimulating foods. During the recovery period when the nail and flesh are separated, avoid touching the wound with water, otherwise tetanus will occur. It is recommended to consult a doctor in time and standardize the treatment and medication under the guidance of a professional doctor in order to avoid delaying the condition.
