Even as a current student in a master's level acupuncture program (that actually takes 3 years to complete), there is so much I did not know about acupuncture. It can be a highly invasive procedure with real risks like pneumothorax and pregnancy loss if done incorrectly. I am friends with a physical therapist who said she used to perform dry needling until she realized her training is not comprehensive enough compared to the safety concerns she is now aware exist. She is no longer willing to risk her patient's safety, or her license for something that isn't truly part of her skillset and I greatly respect that.
