Hypothyroidism: Does it cause joint pain?

Can hypothyroidism cause joint pain? I have hypothyroidism and have been experiencing severe arthritis-like pain in my shoulders and hips.

Mayo Clinic endocrinologist and men's health specialist Todd Nippoldt, M.D., and colleagues answer select questions from readers.

Answer

People with underactive thyroid (hypothyroidism) often have joint and muscle problems due to low levels of thyroid hormone, such as:

Muscle aches, tenderness and stiffness, especially in the shoulders and hips
Joint pain and stiffness
Swelling of the knee joint and small joints in the hands and feet
Carpal tunnel syndrome

Joint problems caused by hypothyroidism are difficult to distinguish from rheumatoid arthritis. Both can cause painful, swollen and stiff joints — often worse after rest. But people with hypothyroidism often have less morning stiffness. They may also have attacks of pseudogout.

Treatment of joint and muscle problems due to hypothyroidism is directed at the underlying thyroid disorder. These problems often improve dramatically with thyroid hormone treatment. Pain relievers may help joint discomfort.

Many people with hypothyroidism have an increased risk of developing other autoimmune diseases, such as rheumatoid arthritis. If pain, stiffness and swelling don't improve after adequate thyroid treatment, consult your doctor.
