Causes

The cause of temporal arteritis is not known. It may result from an autoimmune response in the body. An autoimmune disease is a condition in which the immune system mistakes the body’s own tissue for a foreign invader, attacking and damaging it.

  • Family history
  • Polymyalgia rheumatica—a condition characterized by stiffness and pain in muscles of the neck, shoulders, lower back, hips, and thighs

Temporal arteritis may cause:
  • Scalp pain or tenderness over the temporal artery
  • Headaches
  • Fever or flu-like symptoms
  • Pain when chewing
  • Pain in the jaw or tongue
  • Fatigue
  • Loss of appetite and weight loss
