The common reasons for the symptoms of lumbar pain while sleeping at night are the following: 1. The bed is uncomfortable, too soft or too hard, lacking effective support for the lumbar region, resulting in strain and injury to the lumbar region, leading to painful symptoms. To solve this problem, it is recommended that patients should sleep on a slightly harder bed and put a thin pillow under the waist, which can improve the force on the waist and improve the symptoms. 2, can be seen in patients with lumbar muscle strain underlying disease, during sleep due to incorrect posture or cold and other triggers, resulting in the symptoms of lumbar pain. 3, can be seen in patients with excessive load on the waist during the day, bending too much work or lumbar injury, resulting in local metabolic product accumulation. This leads to local accumulation of metabolites and inflammatory reactions. During sleep, as the overall blood circulation status decreases, blood pressure drops, and blood circulation throughout the body slows, local inflammation cannot be diluted and metabolites cannot be excreted in a timely manner, thus stimulating painful symptoms. If the symptoms persist, it is important to go to the hospital for examination to exclude other diseases such as lumbar infections, tuberculosis, tumors, etc.
