Giant cell arteritis. This condition is an inflammation of the arteries in your head, especially at the temples. It usually occurs in people over age 50. Giant cell arteritis can cause headaches, scalp tenderness, jaw pain, blurred or double vision, and even blindness. It is also called temporal arteritis.
It is important to note that not every organ system will be affected in every patient. The pattern of organ involvement (and symptoms) is unique to the individual, as well as the type of vasculitis (category).
