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 can affect the small-or medium-sized vessels of the skin. Vasculitis affecting the small vessels of the skin (eg, arterioles, capillaries, postcapillary venules) tends to cause lesions such as purpura, petechiae, and possibly shallow ulcers.atients may present with skin symptoms such as lesions, including palpable purpura, petechiae, urticaria, ulcers, livedo reticularis, and nodules. If skin involvement is secondary to a systemic vasculitis, symptoms may also include fever, arthralgias, other organ involvement, or a combination.
