Polyarteritis nodosa is a disorder defined by inflammatory lesions occurring on the medium and small sized arteries of the body. Arteries are the blood vessels, which transfer blood to the organs and tissues of the body. This disorder occurs when the body’s immune system starts to attack the affected arteries. The tissues that are fed by the affected arteries do not receive the necessary oxygen and nutrition required, giving rise to damage. The major symptoms include abdominal pain, decreased appetite, fatigue, fever, joint aches and muscle aches.
