Shortly after my carpal tunnel operation, I met a trained Korean acupuncturist who was also trained as a nurse in Western medicine. She needled me for pain due to carpal tunnel in the other hand and arthritis. I have had no pains from these sources since then, and that was over ten years ago. I was then working at the FDA, and I recall that about ten to twelve years ago, the FDA did have a study on acupuncture and did find that endomorphins were being releases from the punctured sites. Some info on the subject should be available from FDA or/and NIH. The philosophy of acupuncture is quite interesting too and if you could see a map of acupuncture points, you would probably see a well documented map that evolved over several thousand years. I believe it could significantly reduce pain even to the point where it can be used as a sole anesthetic in surgery. Michel
