Painless thyroiditis is also frequently referred to as silent thyroiditis or subacute lymphocytic thyroiditis. It's thought that painless thyroiditis may be responsible for as much as 10 percent of hyperthyroidism, because the typical course of painless thyroiditis is a temporary period of hyperthyroidism, which is then sometimes followed by a period of hypothyroidism, and then a return to normal thyroid function. In painless thyroiditis, your thyroid usually does not become enlarged. Find out more about the signs, symptoms, diagnosis and treatment of painless or silent thyroiditis. More »
