Early symptoms of temporal arteritis may resemble flu symptoms, including such signs as fatigue, loss of appetite, and fever. Due to the eventual inflammation of the arteries, further symptoms include headaches, pain and soreness over the temples, double vision or visual loss, and dizziness or problems with coordination. Pain may also affect the jaw and tongue, especially when eating. Opening the mouth wide may become difficult. Rarely, temporal arteritis can lead to inflamed skin tissue on the scalp.
