Acupuncture needles are very fine, unlike hypodermics, so you do not get the sensation associated with injections.
Most people find acupuncture very relaxing and the only temporary sensation you get on needle insertion is associated with "Daqing" or the drawing of energy to the point.
This may be a felling of warmth or a slight tingling and only lasts a few moments. It means the treatment is underway!
