Hi@microbe1943, @johnbishop and all, Before I was diagnosed with GCA, after my PMR had calmed down, I had severe itching on my torso and scalp. There was no associated redness or rash. When I started on 40 mg of Prednisone, it went away. I used to watch "Mystery Diagnosis". Someone did present with severe itching and the treating doctor said that itching can be a sign of inflammation. We know that PMR and GCA are inflammatory disorders. My experience with itching, microbe1943, seems different from yours, but thought I would share it anyway. Good luck, I hope you get to the bottom of this.
