The prominent symptom of patients with subacute thyroiditis is the pain in the thyroid region. The pain is characterized by increased pain when swallowing or chewing, and the pain can also radiate to the ear, pillow, neck and other parts. Sometimes the pain starts from one lobe and gradually transfers to the other, so subacute thyroiditis is also called creeping thyroiditis. In addition to the manifestations in the thyroid area, some patients may also have systemic symptoms such as fever. The thyroid gland can be swollen, tender, and the swollen gland is hard. Some patients may have symptoms of hyperthyroidism in the early stage, such as panic, nervousness, and weight loss.
