Some patients experience a feeling of self-heating after acupuncture, but it is extremely rare. It is seen in the following situations. There is a possibility that the acupuncture treatment is not properly protected because the muscle is exposed and the acupuncture treatment is performed after the exposure. Patients who develop a slight cold after acupuncture and develop this type of cold and low-grade fever are sometimes mistaken for post-acupuncture fever. Secondly, it is possible that the fever after acupuncture may be due to the fact that during the acupuncture, not only the needling was performed, but also the infrared light was irradiated. Moxibustion treatment was also assisted, or acupuncture treatment with warming techniques was performed. For example, like the classic burning mountain fire method, it is to replenish the patient’s insufficient positive qi, and certain special tonic manipulation treatments may have been carried out, and it is normal for the patient to have this very slight localized heat sensation, or slight heat sensation throughout the whole body at the end of the treatment. It also proves from another aspect that the tonic effect of acupuncture treatment, i.e., the effect of replenishing the body’s deficiency of positive qi, generally does not affect the normal course of treatment of the disease. If there is a slight cold that causes fever because it is not protected during acupuncture treatment, just suspend acupuncture first and treat the fever caused by cold according to the cold. In the clinical acupuncture treatment caused by fever is not rare, so the majority of listeners or patients receiving acupuncture treatment, do not have to worry too much about acupuncture treatment after the emergence of fever.
