Patients who have back pain while sleeping may have more activity in the back area during the day, and the muscle tissue and fascia tissue in the back are damaged, producing excessive acid in the local area, and the lactic acid accumulation is not excreted in time when sleeping, which will produce pain. In addition, if the back area is pressed for a long time when the patient sleeps, it will also affect the blood circulation in the back area, resulting in qi stagnation, blood stasis and obstruction of meridians, which will also cause pain. If the patient has fasciitis, bursitis, interspinous ligamentitis, supraspinous ligamentitis, or lumbar instability in the back area, pain and limited movement may occur during sleep.
