The causes of thyroiditis can be divided into subacute thyroiditis and Hashimoto's thyroiditis,

Subacute thyroiditis is mainly due to viral infections, with apparent tenderness in the thyroid area, and this type of subacute thyroiditis can cause fever. Its treatment mainly involves non-steroidal medications, or steroids can be used during inflammation,

The course of subacute thyroiditis is self-limiting and can be cured, whereas autoimmune thyroiditis is caused by autoantibodies that destroy the thyroid follicular cells, and this type of thyroiditis does not cause fever.
