Hi Rich - it was the neuromuscular doc who didn't believe the poly diagnosed, but has started me on Prednisone for what she called mild myopathy. She said she didn't believe the poly part because most patient's she see's with it are using assistive devices and don't pass the neuro strength exam as well. I don't know what to think of that, except that in all my research I have found that not all patient's present as typical. The NIH also doesn't agree with the diagnosed because of the twitching. It seems twitching could happen with inflammation, but I'm not the doc! Anyway, my twitches are generalized, but also I have had them in some places constantly, like bicep, buttock, abdomen. My jaw feels rather weak and had some twitching, but only for the one day. Maybe the twitches are really from the underlying cause of the myopathy, like if a virus caused it. The rheumo called today and said if I didn't start to improve in the next two weeks she was beginning the chemotherapy drug used for this, I think Methotrexate. Thanks for your post, it helps!
