@runningfree, Please don't feel stupid about asking any medical questions. Questions are how we learn more about our condition and there are no stupid questions. You mentioned none of the tests your doctors supported the Giant Cell Arteritis (temporal arteritis) diagnosis.

"The gold standard for diagnosis is tissue confirmation from a temporal artery biopsy. At the same time, the presence of elevated inflammatory markers such as an ESR or CRP, in combination with symptoms and clinical signs outlined above, may be suggestive of temporal arteritis."

Did you have a temporal artery biopsy?

Hi @runningfree, did you ever get a biopsy of your temporal artery? Did any of your doctors prescribe prednisone? Are your symptoms confined to your head or do you have pains throughout your body? Any fatigue?
