Understanding Myositis: Symptoms, Causes, Diagnosis, Treatment
Myositis refers to a group of inflammatory muscle disorders characterised by muscle weakness and inflammation. There are many causes of muscle inflammation, including infections, drugs induced and autoimmune. In autoimmune causes, the immune system mistakenly attacks healthy muscle tissue. Myositis can affect people of
all ages and is more common in women than men. There are several types of myositis, but the two most common ones are:.
-
Dermatomyositis (DM): It involves both muscle inflammation and skin rash, primarily affecting the face, chest, knuckles, knees, and elbows.
-
Polymyositis (PM): It primarily targets the muscles, causing muscle weakness and inflammation without the characteristic skin rashes seen in dermatomyositis.
