Daily analgesia for nonheadache pain may not lead to daily rebound headaches ============================================================================ * Steve Blitzer I read with interest the article on medication-overuse headache by Micieli and Robblee.1 I have a hard time attributing so many patients’ chronic headaches to medication overuse. I definitely have a group of patients who take analgesics daily (or nearly so), have persistent headaches and have received the diagnosis of medication-overuse headache. I have a similar group of patients who have infrequent headaches, but they do have back pain for which they take analgesics daily. Yet these patients who take an algesics daily for another reason have not had their intermittent headaches turn into daily headaches from analgesic rebound. So why blame the first group’s daily headaches on analgesic rebound or overuse? The second group did not get rebound headaches from daily analgesics. Other factors may be causing daily headaches for these patients. Analgesic rebound, or overuse, seems to be the preferred diagnosis of many clinicians, when it is not necessarily etiologic. ## Footnotes * **Competing interests:** None declared. ## Reference 1.
