Hi you need to go to a doctor. This is what I found on the internet about treatment for vasculitis. Common prescription medicines used to treat vasculitis include corticosteroid and cytotoxic medicines. Corticosteroids help reduce inflammation in your blood vessels. Examples of corticosteroids are prednisone, prednisolone, and methylprednisolone. Cytotoxic medicines may be prescribed if vasculitis is severe or if corticosteroids don't work well. Cytotoxic medicines kill the cells that are causing the inflammation. Examples of these medicines are azathioprine, methotrexate, and cyclophosphamide. Your doctor may prescribe both corticosteroids and cytotoxic medicines. Other treatments may be used for certain types of vasculitis. For example, the standard treatment for Kawasaki disease is high-dose aspirin and immune globulin. Immune globulin is a medicine given intravenously (injected into a vein). Certain types of vasculitis may require surgery to remove aneurysms that have formed as a result of the condition. (An aneurysm is an abnormal bulge in the wall of a blood vessel.)

Ice cream is the cure! :P

Never take any treatment by net!! Only qualified doctor can do it. No selfhealing. I wish you'd follow the advice and go to a doctor instead of asking such questions here.

May be this will help. http://www.nlm.nih.gov/medlineplus/ency/article/000874.htm
