Traditional thinking has been that the lack of sleep is the result of fibromyalgia. Now some physicians are looking at it as the cause instead of the result. Some doctors suspect that fibromyalgia is the result of low levels of progesterone, which causes insomnia, and in turn causes fibromyalgia. The connection is that deep sleep is when the body ‘repairs’ itself. What has led physicians to the insomnia-fibro connection is the low levels of progesterone often found in women with fibromyalgia, which is why more women than men suffer from fibro. Check with your physician to determine if a progesterone creme is appropriate for you.
