Annie59~Thanks for your input. I do have a vitamin D deficiency and I'm sure it could account for some of my symptoms, but not all of them. In particular the weakness I get with exertion, repetitive movements and, in general, the relapsing nature of my illness. Although, I do have some symptoms every day, many days can go by without my other symptoms flaring up.

I've had all the autoimmune blood work done and my CPK levels and other muscle tests have been normal. I'm thinking those would rule out myositis, but, I could be wrong.

Thanks for your input. I do believe in my case, I probably have more than one thing going on. I'm sure this is what is making at least part of my case hard to diagnose.

Thanks again!
