Most patients with chronic headache have a clear cause. Secondary headaches can be cured by removing the cause. Primary headaches can be effectively controlled if a reasonable treatment plan is adopted, resulting in a reduction in the severity of headaches and a decrease in the number of headaches, but most patients cannot be completely cured. Patients are advised to take medication regularly and to follow medical advice to avoid stopping medication at will. Diet and work habits should be strictly observed. With a reasonable treatment plan and diet, most primary headaches can be effectively controlled.
