What are the causes of sacral pain?

Sacral pain is generally caused by sprain of the waist, especially because of long-term bending, which will lead to strain of the waist muscles. The second reason may be that women have gynecological inflammation, such as pelvic inflammatory disease and vaginitis, which will lead to lumbosacral pain. The third reason is because of kidney deficiency, because kidney deficiency will lead to problems in the operation of qi and blood in the body, leading to serious congestion.
