At what age does fibromyalgia typically start in women?

A survey of 100 women with fibromyalgia found that the average woman started experiencing fibromyalgia symptoms at age 46, and menopause had already occurred before fibromyalgia started in two of three women. (In Westernized cultures, menopause is generally expected to occur around age 51.) Although doctors don't know why, studies consistently show that menopause tends to occur nearly 10 years earlier than average in women with fibromyalgia -- around age 42.
