Low back pain can be caused by the following situations: being old, sitting on a low stool for a long time, and getting up the next day will show low back pain; Handling is hard work and easy to flash to the back. At this time, be careful or do something else; Or sedentary, sitting incorrectly.
If you meet the above requirements, I suggest you adjust it quickly, otherwise it will cause you lifelong injury and you can stretch after sitting for a long time. Stay up less. It doesn't matter if you stay up late. The key is to get enough sleep.
I tell you from experience. I don't know if it will help. I wish you a speedy recovery.
