Dr. Scott responded: Multiple causes. The causes of dizziness are quite varied. Most often, there is not a serious underlying condition; however, there are some that are very important to exclude.
Request an appointment. Vasculitis is an inflammation of your blood vessels. It causes changes in the walls of blood vessels, including thickening, weakening, narrowing and scarring. These changes restrict blood flow, resulting in organ and tissue damage. There are many types of vasculitis, and most of them are rare. Vasculitis might affect just one organ, such as your skin, or it may involve several. The condition can be short term (acute) or long lasting (chronic). Vasculitis can affect anyone, though some types are more common among certain groups.
Vasculitis is blood vessel inflammation that causes fever, pain, local tenderness and other evidence of blocked blood vessels. When a blood vessel becomes inflamed and narrowed, blood supply to that area can become partially or completely blocked, cutting off blood supply to the tissues beyond. Inflammation causes the vessel wall to swell. This makes blood stick to the inner wall to form a clot. When vasculitis interferes with circulation in any part of the body, it causes local tenderness and pain. If the blood vessels are close to the skin, characteristic rashes occur. Depending on where the blockage occurs, almost any organ in the body can be affected. (Note: Vasculopathy can also block blood vessels, but it does not cause the fever, pain and local tenderness associated with vasculitis. It may, however, cause pain if the parts that are no longer receiving a blood supply die â a circumstance called infarction.)
