Thanks for posting your query.
you have been diagnosed with vasculitis
which is inflammation of vessels. Vasculitis has many varieties and are usually caused by autoimmune diseases. In this condition vessels get damaged by body's own immune system and may start bleeding inside causing damage to organs or may present with rashes over surface and predispose ulcer formation.
Usually symptoms are controlled by steroids
(predisone), but when it dose not help then other immuno-suppressants and cytotoxic drugs like Cyclophosphamide
may be life saving.
You are advised to visit your doctor and talk about other options of therapy.
Hope it helps.
