Feeling discomfort in the lymph of the neck may be caused by an inflammatory reaction in the local lymph nodes. Most commonly, chronic inflammation of the throat or acute upper respiratory tract infection, resulting in acute pharyngitis, acute tonsillitis, or bronchitis induced lymph node inflammation and enlargement. Usually, local lymph nodes can be hardened and have local pressure pain, and if the inflammation is more serious, the enlargement may also be more serious. However, if the lymph node discomfort is caused by inflammation, the boundary is clear and the activity is high. If the lymph node discomfort is caused by malignant tumor metastasis, the boundary is not very clear and the lymph node activity is not high, but the pain is obvious when pressing. At this time, you can go to the hospital to check the local ultrasound to clarify the specific nature, and if necessary, you have to do local puncture biopsy to confirm the diagnosis.
