I'm at about 5 weeks into P.MR. I had to self diagnosed, cause my Doctor said I didn't have pmr even though I had all the symptoms. Fortunately, I had some prednisone left from a previous prescription that I did not use. So I started treating myself starting at 15 mg which miraculously stopped all my symptoms. I initially wanted to get off the prednisone. And did not do my research enough. And I was reducing very quickly, which caused me to flare so i went back upto 10 mg. And now reducing down more slowly..... But I too also was using collagen every day and sometimes twice a day. I had a funny feeling about this collagen being a possible cause of my PMR. It was very difficult to find a rheumatologist, but I finally was able to get one. And he said that if I had not started on my own, like I did, it would have spread down to my hips.
