There is no doubt PMR is more common. I know my primary care didn't have a clue about GCA...or long term prednisone either. Have you looked at HealthUnlocked.com in the UK under the PMR/GCA group? Since they have national health they have done more research into GCA and fast-track any patient with GCA symptoms. There are also some great Zoom support groups you can join also and talk to people who have been living with it...and doing a great job...for years. Private message me if you are interested. You sure won't feel lonely there!💞
