6. Aches and Pains
Aches and pains caused by hyperthyroidism may affect the muscles and joints of the body. They may also affect certain organs of the body. When the thyroid produces too much of any biochemical substance, the resulting disequilibrium may lead to weakness in the muscles as well as pain. If you have autoimmune thyroid disease, your body may produce excessive amounts of white blood cells that attack parts of your muscle or surrounding blood vessels, causing progressive pain. To treat this symptom, you may use over-the-counter pain medication or prescribed medication by your doctor.
