How does acupuncture work as an analgesic

Question

I understand the whole energy thing about acupuncture and to me, it's a lot like Reiki, and I'm not so sure I believe in stabilizing the body's energy flow. However, I recently went for an acupuncture treatment to write a paper on alternative therapies, and I actually got muscular pain relief from the needling. I didn't tell the practitioner that I had pain in both calves, just the left one. She treated just the left calf along with the energy alignment stuff. The right calf was still sore after treatment, but the left calf was pain free. Later that night, the tops of my feet were numb.

How does needling promote analgesia?

Answer 1

it stimulates the body's endorphines, which are it's natural pain killers.
