Early symptoms of hyperthyroidism usually do not have hard lumps in the neck, and hard lumps in the neck should be considered as thyroid tumors, cervical lymph node metastasis of malignant tumors, lymphadenitis, and lymph node tuberculosis. Early symptoms of hyperthyroidism generally have fear of heat, excessive sweating, fatigue, agitation, irritability, diarrhea, weight loss, etc. The thyroid gland is enlarged, the texture is soft, and it usually does not show up as a hard lump in the neck. When hard lumps appear in the neck, one should be alert to thyroid tumors, lymphadenitis, and lymph node tuberculosis. Thyroid tumors are divided into benign and malignant, which can manifest as hard lumps; cervical lymph node metastasis of malignant tumors usually have symptoms of the primary tumor, lymphadenitis can have local pressure and pain, and lymph node tuberculosis can have symptoms such as low-grade fever and night sweats (abnormal sweating after going to sleep, and the sweating stops after waking up). Patients with hard lumps in the neck should go to the hospital in time to improve ultrasound, CT and other tests, and be treated under the guidance of doctors.
