<unk>  varies in different countries affecting anywhere from 8% to 55.2% of the population. It affects women at a higher rate than men, and<unk>  uses a large amount of healthcare resources around the globe.

Sixty-six percent scored their pain intensity at moderate (5–7), and 34% at severe (8–10); 46% had constant pain, 56% intermittent; 49% had suffered pain for 2–15 years; and 21% had been diagnosed with depression due to the pain. Sixty-one percent were unable or less able to work outside the home, 19% had lost a job, and 13% had changed jobs due to their pain.
