Acupuncture is a pure philosophic approach while the late acupuncturist added some biological concept. From 618 to 906 in the Tang Dynasty text Thousand Ducat prescribe some kind of pain which they called it Ashi-Point which is mean that is the point or painful point (tender point). However, it is the conflict point between both groups the Acupuncturist and Dry needling practitioner. Both searching for painful point under the different name! The Acupuncturist called it Ashi-point while the Dry needling practitioner called it Trigger point!. By the way, The trigger point is not similar as the Tender point! We are as a an acupuncturist familiar with all schools of Acupuncture. If you are looking for an Acupuncture course you are welcome to our School of Acupuncture ECAN (https://www.natural-acupuncture.com)
