Enlargement of neck and throat nodes may be caused by enlarged lymph nodes, acute thyroiditis, thyroglossal cysts, and so on. 1. swollen lymph nodes: bacterial or viral infection of the lymph nodes in the neck can easily lead to inflammation, or lymph nodes can be swollen due to metastasis of local and systemic malignant tumors. 2. Acute thyroiditis: the cause of the disease has not been fully elucidated, and is generally believed to be related to viral infection. The scope of thyroid lesions varies, starting from one lobe and later expanding and transferring to another lobe, and the lesion gland is enlarged, hard, and the pressure pain is obvious. The most characteristic manifestation is pain or pressure pain in the thyroid gland, and often radiates to the submandibular region, behind the ear or neck, and the pain is aggravated when swallowing. 3. Thyroglossal cysts: Thyroglossal cysts are mainly caused by incomplete degeneration of thyroglossal ducts. Abnormal development of thyroglossal ducts will cause relatively soft lumps in the neck. It is recommended to go to the otorhinolaryngology department of the regular hospital for appropriate examination, to clarify the cause of the swelling at the laryngeal node of the neck, and follow the doctor’s instructions for treatment.
