Seems like the studies are a bit of a mixed bag. There was one that confirmed that acupuncture helps headaches and backpain but take that with a grain of salt, since it is pretty much impossible to do a double blind study of a procedure.

IANAD, but it seems like it might do something along the lines of trigger endorphins and alter bloodflow. Meh. Either way, don't underestimate the power of the placebo effect.
