Welcome @michelle1968, Sorry to hear your rheumatologist isn't listening to you or your symptoms. I was fortunate to get a referral from my primary care doctor to a rheumatologist who did listen and got me started on 20 mg prednisone which took away the pain within a few hours of the first dose. I think what makes it difficult is that PMR can be difficult to diagnose and there is no specific test for PMR and there are quite a few different conditions with symptoms that mimic PMR. Here's more information on the topic.

"There's no specific test for polymyalgia rheumatica, but it's likely that a series of blood tests will be done. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are blood tests that can be used to check the levels of inflammation in your body."

There is a great site that has some tips for planning your conversation with your doctor or in this case a rheumatologist - https://www.patientrevolution.org/tools. Have you thought about seeking help or a second opinion at a teaching hospital or a major health facility like Mayo Clinic?
