It's my understanding that there are some studies showing that there may be some small short-term benefits, but that it doesn't matter where the needles are inserted whatsoever. This contradicts the entire theory of 'acupuncture' which states that the needles must be placed in specific spots, believes in meridians, energy and other woo woo. The people I know who are acupuncturists spent about $100K in schooling for it which is a complete scam. It's almost like a religion to them and the things they talk about learning contain very little science whatsoever. Unfortunately the cost ends up being passed along to the patient. I doubt the acupuncture schools want to let the $$$$$$ go.
