The reason for the coldness in the back may be that the Directing Vessel is blocked, or it may be that there is insufficient yang energy in the body. There is little influence with the bladder meridian. According to the theory of meridian science, meridians are the channels through which qi and blood run. Dysfunction of the Foot Solar Bladder Meridian is mainly characterized by lack of warmth at the ends of the limbs. The Duchen Jing is the main channel for all yang qi. When the Duchen Jing is not smooth, yang qi is difficult to be warmed leading to cold spine, or even lumbar and knee weakness (a feeling of soreness and weakness in the lumbar and knee areas), spermatorrhea, and infertility with uterine cold. It can be regulated through massage, cupping or acupuncture. Coldness in the back may also be caused by kidney yang deficiency (lack of yang energy in the kidneys). Kidney yang has the function of warming the organs and organs of the whole body, promoting the production of qi, blood and fluids, and the function of running and transporting. Kidney yang insufficiency will appear to be afraid of coldness, warm limbs, cold pain in the waist and knees, impotence and premature ejaculation, and uterine cold and infertility, and other manifestations. The treatment is based on warming and tonifying kidney yang (warming and replenishing kidney yang), and the specific medication is subject to the physician’s prescription. If the symptoms are obvious, please consult a doctor in time to clarify the cause of the disease and cooperate with the relevant treatment, do not blindly take medication or carry out massage acupuncture cupping and other operations, so as not to cause adverse consequences.
