Is acupuncture effective at treating pain or disorders? I'll give the scientific answer to that question, and explain why I don't recommend acupuncture for any condition.
A few notes, and some references:
1. Toothpick acupuncture does NOT involve inserting the toothpick in the skin. It was merely placed against the skin in a needle guide-tube to give a sharp sensation, then removed.
2. In the USA, acupuncturists are required to meet sterile standards, use one-use-only needles or autoclaved (sterilized) needles, and must be licensed to practice.
3. I'm not really addressing the acupressure and non-insertive traditions of some Japanese acupuncture forms. Certainly these are similar to non-insertive sham treatments, but it should be noted that the placement of fingers or toothpicks is not important for the effect.
