Acupuncture needles are very thin and flexible, quite unlike hypodermic needles used to give “shots” or take blood.  Oftentimes, you cannot feel them being inserted, however at times they might produce a slight pricking sensation.  It is typical to occasionally experience a heavy or mild aching feeling in the area around an acupuncture point.  Please notify me if you are experiencing sharp pain, burning sensation, or numbness and tingling after the acupuncture needle has been inserted.
