Another theory suggests that acupuncture stimulates the body to produce narcotic-like substances called endorphins, which reduce pain. Other studies have found that other pain-relieving substances called opiods may be released into the body during acupuncture treatment. Unlike hypodermic needles, acupuncture needles are solid and hair-thin, and they are not designed to cut the skin. They are also inserted to much more shallow levels than hypodermic needles, generally no more than a half-inch to an inch depending on the type of treatment being delivered. While each person experiences acupuncture differently, most people feel only a minimal amount of pain as the needles are inserted.
Some people reportedly feel a sensation of excitement, while others feel relaxed.
If you experience significant pain from the needles, it may be a sign that the procedure is being done improperly When practiced by a licensed, trained acupuncturist, acupuncture is extremely safe. As a system of health care, acupuncture already has some inherent safeguards. Because the treatment is drug-free, patients do not have to worry about taking several doses of a medication or suffering a possible adverse reaction. Properly administered, acupuncture does no harm. However, there are certain conditions you should notify an acupuncturist about before undergoing treatment.
