As an acupuncturist I get asked this a lot.
The answer is a difficult and involved one. In actual fact, to answer the question of whether acupuncture works really rests on another question: does acupuncture work for your issue?
The answer, if I'm to be truthful, is maybe. Many people find acupuncture effective for them for a wide range of issues and disorders. Some people find that acupuncture does not work for them, and their health issue does not improve from acupuncture treatments. It is important, when looking for an acupuncturist, to call first, or make an appointment for a simple consultation. Ask the practitioner about his or her experience with your particular issue, and whether they've treated it. If they have treated it before, how successful were they? An acupuncturist who does not admit to his or her failures isn't one I'd be inclined to refer to, personally, and I would be wary as a potential patient if my acupuncturist claimed a 100% success rate.
In my practice, eight treatments constitutes a course of treatments, but usually by four treatments both I and the patient can tell whether acupuncture is for them. Often it is, and we continue until the desired results are obtained. However, if the condition hasn't improved after four treatments, I give the patient the option to continue and see what happens, or we can explore other options. As an acupuncturist it is important to know when acupuncture is not working for your patient, and when to refer them to another practitioner or modality.
So the answer to the question of whether acupuncture works can only be answered by really giving acupuncture a good try, which is what any health professional would suggest, medical doctors included. Do your research, and when you've found the practitioner you feel comfortable with make sure you give it a good shot (at least four treatments). As part of your research you are always welcome to send me an email for a free consultation, even if you are not in my area. I'd be glad to help.
