Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.
Autoimmune myositis causes inflammation and weakness in the muscles (polymyositis) or in the skin and muscles (dermatomyositis). Muscle damage may cause muscle pain and muscle weakness may cause difficulty lifting the arms above the shoulders, climbing stairs, or arising from a sitting position.
Rheumatoid arthritis is an autoimmune disease. Normally, your immune system helps protect your body from infection and disease. In rheumatoid arthritis, your immune system attacks healthy tissue in your joints.
There's no cure for myasthenia gravis. However, available treatments usually can control symptoms, allowing those diagnosed with the condition to lead relatively normal lives. In addition, most people with myasthenia gravis have a normal life expectancy.
The main test for myasthenia gravis is a blood test to look for a type of antibody (produced by the immune system) that stops signals being sent between the nerves and muscles. A high level of these antibodies usually means you have myasthenia gravis.
Myasthenia gravis. Myopathy. Myositis, including polymyositis and dermatomyositis.
The main symptom of myositis is muscle weakness, which can start very gradually and cause you to trip or fall over a lot. You may also find it difficult to do things like: get up from a chair. climb stairs.
Autoimmune disorders that specifically affect the muscles, joints, and nerves include rheumatoid arthritis (RA) and multiple sclerosis (MS). Polymyalgia rheumatica, which also involves the joints, is thought to be an autoimmune condition, according to the Arthritis Foundation.
Sudden joint pain that occurs all over the body may signal the onset of a chronic condition, such as osteoarthritis, lupus or fibromyalgia, or even an infectious disease such as influenza or the mumps.
Arthritis is the swelling and tenderness of one or more joints. The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age. The most common types of arthritis are osteoarthritis and rheumatoid arthritis.
Rheumatoid arthritis: This is a chronic inflammatory disorder that primarily affects the joints. It causes stiffness, pain, and swelling. Without proper treatment, it can damage the cartilage and bone within the joints.
The diagnosis of myositis involves a complete physical exam, blood test, electromyography (a neurological test that assess the electrical activity in your muscles), and a muscle biopsy, which involves removing a small sample of muscle tissue for testing.
Common symptoms include fatigue, hair loss, sun sensitivity, painful and swollen joints, unexplained fever, skin rashes, and kidney problems. There is no one test for SLE. Usually, your doctor will ask you about your family and personal medical history and your symptoms. Your doctor will also do some laboratory tests.
Most people with myositis have it for the rest of their lives. People with myositis have an increased risk of developing rhabdomyolysis. Some cases of myositis can be fatal. Around 5% of people with dermatomyositis die within a year of their diagnosis.
Among metabolic myopathies that can mimic myositis are disorders of carbohydrate metabolism such as McArdle's disease, 6-phosphofructokinase deficiency, and Pompe's disease (adult acid maltase deficiency); disorders of lipid metabolism such as carnitine deficiency and carnitine palmitoyltransferase 2 (CPT2) deficiency; ...
Many people described the pain of lupus as similar to having the flu. This means having chills and bone-weary aches throughout your entire body. The pain can be numbing and leave you feeling drained of all energy. “I explain it to others as feeling like the flu: achy joints, muscles, bones.”
Three stages of myositis ossificans: early, intermediate, and mature. Each stage has a unique clinical, radiographic, and histologic appearance.

In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.
The main sign of muscular dystrophy is progressive muscle weakness.
Often referred to as "the snowflake disease," myasthenia gravis, or MG, affects each person differently and likewise, treatment must be individualized. Myasthenia gravis is an autoimmune disease characterized by muscle weakness of the voluntary muscles. The more these muscles are used, the more they weaken.
Lambert-Eaton myasthenic syndrome (LEMS) is a rare condition that affects the signals sent from the nerves to the muscles. It means the muscles are unable to tighten (contract) properly, resulting in muscle weakness and a range of other symptoms.
Beware: there are other diseases that mimic myasthenia gravis. A number of disorders may mimic MG, including generalized fatigue, amyotrophic lateral sclerosis (ALS), Lambert-Eaton myasthenic syndrome, botulism, penicillamine-induced myasthenia, and congenital myasthenic syndromes.
