Hi @lynd, if Giant Cell Arteritis could be diagnosed with blood tests, then a biopsy of the temporal artery would not be necessary. Tenderness of the scalp is one of the symptoms, as is jaw pain, difficulty chewing, visual disturbances, headaches. I also had an itchy torso with no rash, a dry cough, especially at nights, extreme fatigue, due to anemia, a very stiff neck with pain that went up both sides of my head, and short stabbing pains in my face from the ear to the nose. The day before my biopsy I counted 25, Untreated, GCA can cause blindness or stroke. It requires a higher dosage of prednisone than PMR. Can you get a referral to a rheumatologist?
