Hi,
I spent 10 months suffering from pain I knew to be totally consistent with PMR. I'd had it for about 3 years 12 years previously. The Rheumatologist would not accept it was PMR because I did not have raised levels of CRP or ESR. It was only after my GP tested and ruled out for a whole range of conditions whose symptoms overlap with PMR that the Rheumatologist finally agreed I did have PMR. He had finally also deigned to read the extracts for medical journals I had found that showed that something like 20% of people with PMR do not have the associated blood markers.
