My primary care physician diagnosed me with PMR. She wanted me to see a rheumatologist who gave me a large battery of tests to determine if I had another autoimmune disease. He also did numerous X-rays. In the end he said it was PMR. He has treated me with various drugs and biologics that my primary MD could not prescribe. A good rheumatologist is worth their weight in gold. He also spends a good deal of time with me every 3 months, never hurries me away.
