While we’re on the subject…
I found this video on YouTube.com. The narrator, Michael Shermer, seems to approach the subject with a healthy skepticism--I like how he doesn't dismiss acupuncturists (and patients) as fools. He seems to take the most issue with practioners' claims that acupuncture can help alleviate certain conditions, conditions that have not been shown to improve at all due to acupuncture.
What he does allow is that there seems to be some relief for chronic pain patients--and this is why it seems appropriate to post the video here.
Can you tell when a migraine attack is coming?
