Doctor: The data that you provided in your question is very vague and no specific, then, I will answer in a very general manner r. There are many causes of muscle swelling or inflammatory myopathies. Myopathy is a term used to describe muscle disease. The inflammatory myopathies are a group of diseases that involve chronic muscle inflammation, accompanied by muscle weakness. Another word for chronic inflammation of muscle tissue is myositis. Muscle inflammation may be caused by an allergic reaction, exposure to a toxic substance or medicine, another disease such as cancer or rheumatic conditions, or a virus or other infectious agent. The chronic inflammatory myopathies are idiopathic, meaning they have no known cause. They are thought to be autoimmune disorders, in which the body’s white blood cells (that normally fight disease) attack blood vessels, normal muscle fibers, and connective tissue in organs, bones, and joints. The diagnosis is based on your medical history, results of the physical exam and tests of muscle strength, and blood samples that show elevated levels of various muscle enzymes and autoantibodies. Diagnostic tools include electromyography to record the electrical activity that controls muscles during contraction and at rest, ultrasound to look for muscle inflammation, and magnetic resonance imaging to reveal abnormal muscle and evaluate muscle disease. A muscle biopsy can be examined by microscopy for signs of chronic inflammation, muscle fiber death and vascular abnormalities.
