Chinese medicine believes that kidney deficiency can lead to lumbar pain, but lumbar pain can also be caused by other diseases, even in the absence of disease, overexertion can also lead to lumbar pain, so you can not rely on a symptom of lumbar pain alone to confirm the diagnosis of kidney deficiency. Kidney deficiency refers to the deficiency of kidney essence and yin and yang, the most common being kidney yin deficiency and kidney yang deficiency. When the kidney is deficient, it will cause lumbar soreness, which is manifested by lumbar weakness and limb weakness, but at the same time there may also be dizziness, tinnitus, deafness, sunken and weak pulse, etc. To confirm the diagnosis of kidney deficiency, we need to combine the patient’s specific symptoms and pulse to make a judgment. In addition, the manifestation of soreness in the lower back may also be due to lumbar muscle strain, lumbar disc herniation and other diseases. Therefore, when there is soreness in the back, you need to go to the orthopedic department or Chinese medicine department of a regular hospital in time to be judged by a professional doctor whether it is kidney deficiency, do not self-diagnosis, so as not to delay the treatment of lumbar muscle strain, lumbar disc herniation and other diseases.
