"National survey data that provide detailed data on use of treatments are limited. Of the common pain conditions, sufficient details have only been reported on migraine headaches. Recent data indicate that only 41% of individuals who have migraine headaches in the US population ever receive any prescription drug for migraine. Only 29% report that satisfaction with treatment is moderate, especially among those who are often disabled by their episodes. Randomized trials demonstrate that optimal therapy for migraine dramatically reduces headache-related disability time in comparison with usual care."
