Myositis is a disease with different forms that include dermatomyositis, polymyositis, juvenile myositis and inclusion-body myositis. Myositis is one of the rarest of the autoimmune diseases diagnosed in just 1 in 100,000 people a year. It is hoped that raising the awareness of the condition will shorten the time that it takes to get a diagnosis.
Myositis describes a number of idiopathic myopathies that inflame the muscles that move the body. Diagnosis is often delayed because the symptoms are also common in many other muscle diseases. Myositis Awareness month is now in May each year to raise awareness of myositis, it's symptoms and treatments.
