Does Acupuncture hurt? The short answer is no, the long answer is maybe. In general, patients either feel nothing or a very slight twinge during acupuncture.
Acupuncture needles are much finer than a hypodermic needle; about 20-30 acupuncture needles could fit inside a hypodermic. Acupuncture needles are also solid, while a hypodermic is hollow. Hypodermics gouge out a piece of flesh while acupuncture needles do not.
