Some symptoms of myositis include muscle weakness, pain, difficulty moving limbs and fatigue. Myositis refers to the inflammation of the muscles that are used in movement of the limbs, notes MedlinePlus.
Myositis is most commonly caused by injury or infection. In certain cases autoimmune diseases, such as rheumatoid arthritis and lupus, may cause myositis. Individuals that take certain medications and illegal drugs are at a risk of getting myositis.
The most common symptom of myositis is weakness in the muscles that help control limb movement. Painful sensations in the muscles may sometimes occur. Individuals with this condition sometimes find it hard to breath or swallow food. Increased risk of falls and general tiredness are other symptoms that may indicate myositis.
A doctor is likely to take the patient's history before carrying out a physical examination of the patient. Other tests that may help ascertain the condition include an MRI, blood tests and a muscle biopsy. There is no treatment currently available for this condition, notes the Arthritis Foundation. However, doctors focus on managing symptoms as a way of providing relief. Stopping certain medications, antibiotics and treating an underlying cause are just some of the options available for managing the condition.
