The Kidneys are stored internally and externally correspond to the lower back. Wherever the lower back is, there the Kidneys reside. Only when sexual activity is not regulated and the True Essence (Zhen Jing) is exhausted, causing the Kidney organs to become empty, does the lower back lose its vigor (Note: Original text "腰斯雄健" implies vigor, but context suggests pathology; translated as losing vigor based on medical logic). Damaging the True Yuan (Primordial Qi) leaves diseases to manifest in later years.
There is lower back pain caused by Blood Stasis, resulting from falls, drops, or impacts affecting both sides of the lower back, causing pain that is lighter during the day and heavier at night, with a Choppy (Se) pulse. There is lower back pain caused by Damp-Phlegm, triggered by sitting for long periods on cloudy days or due to a diet rich in rich and sweet foods, with a Slippery (Hua) or Deep/Fixed (Fu) pulse. There is also lower back pain caused by sprains or strains; if there is Kidney Deficiency without a solid foundation, a slight sprain can cause the Kidney to displace from its original position, presenting with a Full (Shi) pulse. This is how such pain arises. There is lower back pain caused by chronic diarrhea, where the depletion of fluids leads to the drying up of True Yin Water. Why is the lower back heavy as if bound by five thousand coins? The Kidney belongs to Water, and its nature is inherently heavy. When combined with Spleen Dampness sinking downward, Dampness and Water share the same palace; Water overflows when combined with Dampness, which is why the lower back feels heavy. However, if it is only heavy and not very painful, it is because the Kidney Water fails to consolidate.
In women, lower back pain in the young and strong is often due to Blood Stagnation, while in the elderly, it is often due to Blood Deficiency. If a woman experiences lower back pain before labor, it is because the membranes of the uterus are about to detach from the Kidney. To treat this disease, one must examine whether it is Excess or Deficiency, and treatment will be accurate.
The pulse of lower back pain is mostly Chen (Deep) and Xian (Wiry). Chen indicates Qi Stagnation; Xian indicates Kidney damage; Ru Xi (Soft and Fine) indicates injury by Dampness; Se (Choppy) indicates Blood Stasis; Hua (Slippery) indicates Phlegm-Fire; Hong Da (Surging and Large) indicates Kidney Deficiency. A pulse that is Chen and Slippery is easy to cure.
