Acupressure is a treatment based on acupuncture, but without the needles. The concepts and the practice are otherwise the same. If you are afraid of needles, as I am, it is possible to get the benefits of acupuncture without the needles.
I recently attended a seminar about acupressure with Mahsin, who manages Acuviva in Geneva. Educated as a nurse, she was trained in acupuncture in Colombo, Sri Lanka years ago.
