I saw a lot reviews said “dry needle” is useful. Absolutely working because “dry needle” is “Ashi style Acupuncture”. Acupuncture have “meridian style acupuncture”, “ashi style acupuncture” and other style acupuncture. “Ashi”refers to a painful point that is tight and is tight and tenderand they are palpated locally or distally in the area of pain, aching or tightness. Obviously to practice dry needle treatment is to practice acupuncture.
