The pain you are currently in is exponentially more agonizing than the hair-thin dry needles we use. The needles we use are very fine, about the width of a single strand of hair. In fact, you can fit 14-20 acupuncture needles inside the shaft of your typical hypodermic needle! You should feel a tingling or spreading sensation or sense of heaviness when the needle goes into deep tissues. But you should never feel stinging, burning, or pain.
