What is the cause of one side back pain?

There are many reasons for one side of low back pain, and the following are common: 1. It may be that the sleeping posture is not good or other reasons, causing the pressure on one side of the waist to be too large, exceeding the normal bearing range of the waist, which may cause one side of low back pain. 2. It may be due to lumbar displacement. When the lumbar displacement presses the local nerve, it will cause low back pain, and it will be accompanied by symptoms of muscle tension in the pain area. 3. It is caused by excessive amplitude of waist activity during exercise and damage to the muscles of the waist. In addition to low back pain, this situation will also be accompanied by local muscle tension and limited movement of the waist. It is also possible that the waist has a history of trauma, resulting in congestion in the waist.
