Vasculitis refers to inflammation of the blood vessels. Vasculitis can result in poor blood flow to tissues throughout the body, such as the lungs, nerves and skin. Thus, vasculitis has a wide range of signs and symptoms , such as:
Shortness of breath and cough
Numbness or weakness in a hand or foot
Red spots on the skin ("purpura"), lumps ("nodules") or sores ("ulcers")
On the other hand, vasculitis of the kidneys may produce no symptoms at first but is still a serious problem.
Vasculitis can be mild or disabling, or even lead to death. Patients can have one episode of vasculitis or have repeated episodes over several years. Most types of vasculitis are rare.
