How many people have fibromyalgia in us?

Caution: Because fibromyalgia is a syndrome based on signs and symptoms with no known cause, it is difficult to be accurate. We see a lot of over and under diagnosis. I have seen estimates anywhere from 6 to 18 million people with fms in the United States.

12 Million: 4% of population. Interestingly, incidence transcultural & across populations. This suggests fundamental human frailties that potentiate fibromyalgia. These data implicate common biomechanical injuries afflicting all humans, i.e., multiple childbirths & most common injury of humans - low back and pelvic girdle injuries and mundane mechanical back-pelvic injuries of lifting & pratfalls (shipman).
