What is Myositis?

Myositis is a term used to describe inflammation in the muscles. This condition may be caused by injury, infection, or autoimmune conditions. 

There are several categories of Myositis:

1. Inflammatory: A condition that causes inflammation throughout the body has the potential to affect the muscles, thus causing the inflammation. A majority of these involve autoimmune conditions. Autoimmune diseases describe an event where the body attacks its own tissues. Some of the autoimmune conditions that may cause myositis include:
2. Rheumatoid Arthritis
3. Scleroderma
4. Lupus
5. Infection: Viral infections are among the most common illnesses that can cause myositis. These viral infections include flu, cold, and HIV.
6. Drugs: There are several medications and illicit drugs that can cause temporary damage to muscles. Some of these include alcohol, Plaquenil, statins, and cocaine.
7. Injury: Intense workouts can cause swelling and pain in the muscles. This can last anywhere from several hours to several days after a workout.
