Myositis means inflammation of the muscles that you use to move your body. An injury, infection, or autoimmune disease can cause it.

Who is most likely to get myositis?

Adults between the ages of 30 and 60, and children between the ages of 5 and 15 are more likely to get myositis.

Does stress cause myositis?

For those of us with chronic autoimmune diseases, such as the idiopathic inflammatory myopathies, generally referred to as myositis, stress can be even more damaging. It has been shown that stress can diminish our immune system, cause disease, and increase inflammation.
