Truly nothing to fear! For most people the word “needle” brings to mind that hated and feared IV needle from the hospital, or that last blood draw that they couldn’t find the vain and just poked around inside your arm, or how about that tetanus shot that felt like a 10 penny nail was just driven into your arm. Really I do understand! I have been on the receiving end of all of my examples so when I say you have nothing to fear I promise that you have nothing to fear. The acupuncture needles in my office are 0.16 or 0.30 millimeters thick, about the thickness of a human hair.
