Hi @123suew, I had about 3 -4 weeks of itching on my torso and scalp a month or so before I was diagnosed with GCA. It hasn't returned since I've been on prednisone. Itching is not one of the symptoms I've seen associated with GCA in articles I've read, but itching is a sign of inflammation and both PMR and GCA are inflammatory disorders.

In the past, whenever I used a deodorant that had aluminum chloride (I think that's what it is) I had severe itching under my arms. Have you changed any of your hygiene products lately?

I hope that helps.
