Neurodermatitis, known as chronic lichen simplex, is a difficult condition to treat, and only some patients can be cured when the triggers are eliminated. Whether or not chronic lichen simplex can be cured has a lot to do with whether or not the triggers are eliminated. Generally speaking, if the disease is caused by excessive consumption of stimulating foods, alcoholism, excessive washing of the skin, exposure to certain chemicals, etc., it can be cured through active treatment after eliminating the triggering factors, and the chances of recurrence are relatively low if the patient is well-protected in his/her daily life. If the cause of the disease is not clear, or related to severe anxiety, depression and other neuropsychiatric factors, endocrine disorders and other reasons, and the condition is more serious, it may not be cured, or although temporarily cured, but easy to recur later. Chronic lichen simplex moss can cause severe itching when it flares up. In order to minimize the impact on work and life, patients should actively cooperate with their doctors, remove the triggering factors as much as possible, and relieve the itching symptoms.
