There is no solid theoretical basis behind acupuncture. Reviews of acupuncture research indicates that most of the research is of poor quality and the better research shows that it doesn't work any better than placebo (sham) acupuncture. As time passes a health problem may away of its own accord, or ebb and flow. So, multiple treatments or giving the treatments time to work, may not be at all related to feeling better. I mention all of this with reservation but I see too many people waste too much money on treatments that don't address the underlying problem and acupuncture is not without risk. I think it is worth looking at the science.
