It is necessary to go to the hospital as soon as possible to complete relevant examinations, identify the causes of lymphadenopathy, and give appropriate treatment. Generally, blood routine examination, C-reactive protein, color ultrasound, etc. are required. If bacterial infection is considered to be the cause, antibiotics should be given for treatment. Common drugs include cephalosporins, such as cefalexin and cefuroxime. If it is considered that it is caused by virus infection, antiviral drugs, such as ribavirin, should be given for treatment. At the same time, traditional Chinese medicine can be used for treatment with good effect. If it is considered to be caused by allergic factors, it is necessary to actively get rid of the allergen and take oral desensitization drugs for treatment, such as cetirizine. Try not to drink alcohol and eat spicy food during treatment.
