I went undiagnosed for 6 months and my PMR started with a frozen right shoulder. I went thru physical therapy for 4 months. Had trouble with walking and no diagnosis from my primary doctor. Finally had an MRI after 5 months into therapy. Saw an orthopedist who diagnosed PMR. Immediately after getting a super shot for the shoulder I could walk much better. The orthopedist called my primary dr. to give his opinion. I’ve been on prednisone since, starting at 20mg and being reduced to 5 mg. That didn’t work well and the pain returned. I’m working on cutting down again, but doing better. Not happy that it took 6 months of pain and therapies that did not really help enough. I was very disappointed in the lack of diagnosis. I believe any dr who is a good diagnostician is worth their weight in gold.
