It typically causes inflammation of the network of small vessels (vasa vasorum) that supplies the larger arteries. It may occur together with polymyalgia rheumatic.
General Symptoms includes severe headaches, pain and tenderness over your temples and scalp. Pain in the jaw after chewing (called jaw claudication), fever and blurred vision are some other symptoms. The treatment for GCA should begin as soon as possible because of the risk of loss of vision.
