When I talk to people about Acupuncture, one of the biggest concerns is with the needles: How big are they?Â
Â
Acupuncture needle sizes are tiny. They are thin & flexible; if you flick them with your fingers, they will wobble back & forth. Compared to a hypodermic needle, which is a needle used to give an injection, you can fit about 10 acupuncture needles in the tip of one hypodermic needle.Â
Â
So if you’re worried about how big they are and think you will feel something akin to getting a shot, you will be happily surprised to find that an acupuncture needle insertion is absolutely nothing like getting a flu shot. It is almost always painless (there are some exceptions). Also note that once it’s in, it’s in. As long as you don’t move, you won’t feel a thing. There is also no injectable, so no secondary pain.Â
Â
Hopefully this gives you some peace of mind about needle insertion during acupuncture.Â
