Because each patient’s health problems and response to treatment are unique, the number and frequency of treatments vary. Typically, the recommendation is two to four treatments per week for eight to sixteen treatments, although some patients respond favorably after only one or two treatments. Some may not improve until the eighth or ninth visit. Others may require two or three treatments per week for several months for maximum results. And sometimes, despite the acupuncturist’s best effort and skill, the patient does not respond to treatment. In general, acute conditions require less treatment than chronic conditions.
