I hope you don't mind my response to your question. I had symptoms of GCA for a few months without knowing what they meant. I had a low grade fever that slowly increased in duration from a few hours per day to most of the day. I also had night sweats, pain in my cheekbones and around my ears, and a lot of fatigue in my jaw muscles when I was chewing. I finally went to the emergency room when I lost the vision in one eye for a few seconds. It was like looking at a blank gray wall. My vision "glitched" several more times while I was at the hospital. Those episodes were like looking at an impressionist painting where some colors disappeared and others became more dominant. After running a lot of tests, the emergency room doctor diagnosed GCA. I was admitted to the hospital for 3 days to receive daily infusions of high dose steroids. That saved my vision. In the 6 months since I've been taking prednisone and Actemra, and haven't had any more symptoms of GCA or PMR.
