Most swollen lymph nodes will not kill you, because the most common cause of swollen lymph nodes is bacterial infection or viral infection. You need to go to the hospital to improve relevant tests, such as blood routine, C-reactive protein, and ultrasound. According to the test results, the condition can gradually improve with regular medication. However, for more serious infections, it may lead to high fever, chills, and even sepsis and bacteremia, which may be fatal. If the patient is caused by a hematologic disorder, such as lymphoma or malignant tumor lymph node metastasis, this may also be fatal at that time. Therefore, after finding swollen lymph nodes, it is necessary to go to the hospital as soon as possible to improve the relevant examination and, if necessary, to do lymph node puncture biopsy or excisional biopsy to clarify its nature. During the examination and treatment, patients should not drink drinks containing alcohol or eat spicy food, etc.
