Acupuncture is virtually painless! The majority of our patients say they hardly even feel it. It surprises many people because most people’s experiences with needles consists of getting injections or blood drawn with hypodermic syringes. Acupuncture needles are completely different. Acupuncture needles have a solid, filament-type structure. While there are many gauges of acupuncture needles, they are all very fine — a fraction of a millimeter wide — so almost as narrow as a hair or about the thickness of cat whisker. In addition to being so much narrower, nothing is being injected or drawn.
