Myositis is a condition in which your immune system attacks your muscles. It creates persistent inflammation, which causes swelling that comes and goes over time. This inflammation eventually causes your muscles to feel weaker. It can also result in muscular soreness.
Myositis usually affects the muscles you use to move, including muscles in your:
- Arms and Shoulders
- Legs and Hips
- Abdomen and Spine
Polymyositis affects numerous muscles at once. It frequently shows up itself in muscles around or in the centre of your body.
Polymyositis shows itself progressively over time. Adults are more commonly affected. Women and persons designated female at birth are twice as likely as males and those assigned male at birth to develop polymyositis.
Dermatomyositis is a kind of myositis that affects both your skin and your muscles.
Some instances develop over months, while dermatomyositis can appear suddenly. The sooner you begin therapy, the more probable it is that you will prevent serious consequences.
Dermatomyositis can be deadly in rare situations, particularly in the first year after symptoms appear. It can also boost your chances of getting some types of cancer.
Inclusion Body Myositis :
Inclusion body myositis is a muscle condition that causes degeneration. It often affects adults over the age of 50.
Muscle weakness in the extremities (hands and legs below the knees) is caused by inclusion body myositis. It can also have an effect on the muscles in your throat that aid in swallowing. Dysphagia (difficulty swallowing) affects around 30% of persons with inclusion body myositis.
Myositis symptoms include:
- Muscle weakness.
- Joint or muscle pain
- Trouble breathing or swallowing.
- Arrhythmia (if the myositis affects your heart)
There is no sure way to avoid myositis ossificans. However, you can lower your chance of nonhereditary myositis by appropriately treating injuries, especially if you have a significant bruising or swelling. Use the RICE treatment immediately after an injury. RICE is an acronym that stands for:
Reducing your risk of injury may also lower your chances of developing myositis ossificans. Injury prevention requires proper fitness, stretching, and enough rest.
