Introduction
Basedow’s disease is the most common cause of thyrotoxicosis.1 Thyrotropin receptor antibody (TRAb) is produced on the surface of the thyroid gland as an autoantibody against the binding receptor of thyroid stimulating hormone (TSH). TRAb overstimulates the TSH receptor instead of TSH, causing excessive production of thyroid hormones that subsequently causes Basedow’s disease.1Abnormally high levels of thyroid hormones that increase the metabolism of the entire body can have significant health consequences. Known autoimmune mechanisms include orbital disease, goitre, and thyroid dermatosis. 2Symptoms of Basedow’s disease can be caused by either hyperthyroidism or autoimmune mechanisms. Hypothyroidism commonly causes myalgia in thyroid gland dysfunction.3 Herein, we report a case of Basedow’s disease that presented with a rare complaint of myalgia.
