I agree that stretching is a must!
What helped me the most was increasing my dose of generic T3 thyroid medication (liothyronine) until my TSH was well into hyperthyroid territory, but with no symptoms of being hyper. That reduced the muscle pain by 85% at least.
Creatine powder, 5 grams in water, drunk before any exertion, is also very helpful, and increases strength and endurance. this is esp. helpful if you don't eat much meat, and I don't.
Doctors to look up who can explain the thyroid problem best are Dr. Lowe, Dr. Rind, Dr. Derry, and Dr. Holthorf, among others. I would also look up Mary Shomon, who has written "Stop The Thyroid Madness" an excellent book on this, and who has posted much useful info online.
I used to think these docs were nuts when they said they felt hypothyroid, ie. a low metabolic state was the main component of CFS and FMS, but now I am not so sure, since I got such dramatic results, even being able to drive a car again for short distances.
They point out that CFS and FMS appeared suddenly, 6 years after the "useless" TSH test was adopted as the gold standard, rather than just treating the symptoms until they went away like before, and that TSH is very slow to change to reflect what is going on in the body, so 6 yrs. is just about right for the problems with using TSH instead of treating symptoms to start showing up.
This tx also got rid of about 75% of my fatigue as well. (I have a systemic yeast problem from what Lyme did to my immunity that I feel accounts for the rest of it, and am getting prescription tx for that, but with not much success).
