Hi @5333, I was diagnosed with GCA and had PMR for a year previously. My diagnosis was confirmed by temporal artery biopsy. I had short stabbing pains from my ear to my nose, some problems seeing out of my right eye tro and a severe very painful stiff neck. The rheumatologist perscribed 40 mg prednisone, based on my size, about 100 lbs.
What I've learned from this site is that most that are diagnosed with PMR are toldd to be on the alert for symptoms of GCA. In this circumstance, you were correct, I think, in upping you dosage of prednisone. As @johnbishop and @emo mentioned, it's best for you to see a rheumatologist as soon as possible. I wish you the best!
