I was having persistent lower abdominal pain months after some surgery and had allopathic doctors basically assume I was barking at them for painkillers and flick me away so I gave homeopathy a try. I had 3 different acupuncturists over the several months I gave it a shot. There was no consistency to how they placed needles, and all of them explained the rationale behind their placement completely differently. It really had no effect on the pain that laying in a quiet room with a heat lamp pointed at my stomach wouldn't have. I'll admit to having weird moments where s/he would stick a needle in my leg and I would feel it in my ear or get a little zap somewhere or something like that, but that's not really treating anything--it's just interesting.
Frankly, I think it's bullshit but some people swear by it, and if you think it's working that's really all that matters.
