Vasculitis

 Vasculitis is a blood vessel inflammation. This happens when the body's immune system accidentally attacks the blood vessels. This can happen because of an infection or other illness. The cause is often unknown. Vasculitis can affect the arteries, veins and capillaries. Arteries are a vessel that carries blood from the heart to the body's organs. Veins are the blood-carrying tools back to the heart. Capillaries are tiny blood vessels connecting the small arteries and veins. Symptoms of vasculitis can vary, but most often include fever, swelling, and a general feeling of bad feeling. The main purpose of treatment is to stop the inflammation. Steroids and other anti-inflammatory drugs are often helpful.
