What is Muscle Arthritis?

The medical term for muscle tissue inflammation is myositis. Dermatomyositis is one form of muscle arthritis. Without the accompanying rash, it is called polymyositis.


In myositis, there is pain, inflammation and soreness in the muscles. There is also a dry rash on the shoulders, back, chest, neck and face. The condition may affect heart muscle and lung tissues. The rash is usually of a purplish-red, dusky color. It is an autoimmune condition and can be treated with anti-inflammatory medicines such as steroids.


This is another type of muscle arthritis. Symptoms include muscle aches and pain in the connective tissues and joints. It could also lead to sleep problems, anxiety, headache, depression and fatigue. About two percent of the population has fibromyalgia. Treatment includes medications to relieve pain and other symptoms. Fibromyalgia-specific medicines are now available in the market and can be prescribed.


Lupus usually affects the joints, but some patients suffer muscle pain and aches. Treatment includes corticosteroids and related immune system modifiers. Symptoms include rash on the face, multiple joint arthritis, fatigue and fevers. Lupus is an autoimmune disease, that occurs more in men than women.

Polymyalgia Rheumatica

Symptoms are muscle pain near the neck, shoulders or hips. It can occur very suddenly. The condition is characterized by high red blood cell sedimentation rate. It most often occurs with a vascular ailment called polyarteritis or with giant cell arteritis, which causes inflamed blood vessels. Prompt treatment cures both conditions. Corticosteroids like prednisone and nonsteroidal anti-inflammatory medicines are prescribed.


This is a side effect of medications prescribed to lower cholesterol, called statins. It can have serious ramifications such as heart and kidney damage. Patients taking statins therefore need to ensure that they report any unexplained muscle pains or aches to their doctors.

  1. Your website stated “another type of myositis is Fibromyalgia.” Fibromyalgia does not include inflammation, which is what “itis” means. Fibromyalgia is muscle PAIN, not inflammation. That’s not to say that you can’t have inflammation, but it is a different condition, not Fibromyalgia, usually brought on by muscle strains (overuse), repetitive motion, etc. I’ve had fibro for 20+ years and have studied it extensively. That’s why the name was changed many years ago from “Fibrositis” to “Fibromyalgia.”
