As @jabrown0407 pointed out, GCA is strange in that those who have it may experience different symptoms. I had it once, then relapsed and my symptoms were different both times. I had a tender scalp, sharp, shooting pains from my ear to my nose (one day I counted 25), and visual disturbance in my right eye (could only see white) three times.
Second time around, it was extreme pain in my neck and up my head, like pressure or tightening. I was fortunate to not lose any vision. I experienced loss of appetite both times and a tender scalp.
It's helpful to document everything so you can give your doctor an accurate account.
Good luck, @scottschooley!
