Post polio literature has for many years, mentioned polio survivors experiencing fibromyalgia. In Western Australia we have been successfully treating this with large doses of supplemental magnesium chelate. Taking this with Vitamin C is helpful to control the pain and help absorption. Manganese stops the stiffness we get after sitting for a while.
Magnesium, boron and castor oil can be very helpful when massaged on to the skin.
