If the lymph nodes do not go away for several years, you need to go to the hospital as soon as possible to improve the relevant examination to clarify the cause of the disease, usually need to check the blood routine, C-reactive protein, calcitoninogen, ultrasound, etc.. If bacterial infection is the cause, antibiotics such as cephalosporin and penicillin should be given for treatment. If a viral infection is considered, antiviral drugs should be given to treat the infection, along with Chinese herbal medicine, which is more effective. If tuberculosis is considered to be the cause, anti-tuberculosis drugs should be given and rest should be increased. If there is no obvious organic lesion, there is no need to worry too much at this time, just control the diet and increase exercise actively. Do not drink alcoholic beverages as much as possible, consume fresh fruits and green vegetables, and choose swimming, jogging, tai chi, yoga, etc. for physical exercise.
