Causes of enlarged lymph nodes include inflammation, tuberculosis, tumors, and hyperplasia. more than 90% of enlarged lymph nodes are due to inflammation, so most of the enlarged lymph nodes do not require special treatment. If the lymph node enlargement is accompanied by obvious pain, you can take oral cephalosporin anti-inflammatory drugs for 5-7 days, such as cefdinir, cefixime and so on. If the lymph nodes are enlarged without pain and have relatively good mobility, most do not require any treatment. If the lymph nodes are hard to the touch and have poor mobility, it is recommended that an ultrasound be done as soon as possible to rule out the possibility of tuberculosis and tumors. Of course, if you want to make sure that it is not tuberculosis or tumor, you can do lymph node biopsy if necessary.
