Newswise — An estimated 12.1 million women age 18 and older reported suffering from chronic pain in 2008 as a result of underlying medical conditions such as chronic fatigue syndrome, endometriosis, fibromyalgia and vulvodynia. Of these women, only 8.7 million reported receiving treatment that year at a total cost of $12.9 billion, according to the latest News and Numbers from the Agency for Healthcare Research and Quality.

Among other findings:

• About 11.2 percent of non-Hispanic white women, 8.3 percent of non-Hispanic black women and 8.2 percent of Hispanic women had one or more of these chronic pain conditions; 8.4 percent, 5.4 percent and 5.5 percent received treatment for them, respectively.

• Of the $12.9 billion in total expenditures, nearly half ($5.7 billion) was spent for treatment in ambulatory settings such as a doctor’s office and another $2.4 billion was spent on prescription medicines.

• Among women age 18 to 64, nearly 15 percent of their medical expenses was paid out of pocket while private insurance paid 68 percent; Medicaid, 10 percent; Medicare, 3 percent; and other sources, 4 percent.
