Between Joint

What is Polymyositis?

Polymyositis is an inflammatory disease that targets skeletal muscles, causing them to become weak, stiff, and painful. It is caused when the immune system mistakenly starts attacking healthy cells and tissues of the body. The cause of this autoimmune disorder is still unknown.

The most common symptom of polymyositis is severe joint pain that is caused by the immune system attacking connective tissues and muscles near the joints. ThisResults in inflammation, redness, and swelling of the affected area which can limit joint function. Over time it can also lead to deformity and disability.
