I went through something very similar to you. It took 4 months to diagnose my PMR and a GP who said I was just anemic, my radiologist ( from breast cancer ) who referred me to my oncologist who referred me to a neurologist who was the one who diagnosed PMR, Luckily he was in the same medical complex as the rheumatologist so I got in straight away. He put me on Prednisone immediately and by the next morning I was pain free. I guess not many doctors are familiar with PMR, but it seems that there is a kick off point that starts it, either a vaccination or, as i my case, a strong antibiotic after a colonoscopy. I do wish you luck in your diagnosis - 'though I wouldn't wish PMR on anyone.
