If the symptoms of lumbar pain appear after sleeping for a long time, the following conditions may exist: 1. The usual stimulation by cold, cold, overwork, traumatic fall or prolonged maintenance of a fixed posture may cause damage to the fascia of the lumbar region thus causing local inflammation resulting in fascial adhesions, and a significant reduction in the activity of the lumbar region during sleep will lead to an increase in the degree of fascial adhesions; sudden activity of the lumbar region after waking up with lumbar pain The symptoms are due to the adhesion of the fascia, and the adhesion of the fascia will be torn during the activity. 2, if the poor sleeping position will lead to damage to the lumbar intervertebral ligaments, lumbar muscles or lumbar joints and even lumbar discs, there will be lumbar pain after waking up. 3, if the sleeping bed is too soft, there will be obvious deformation of the lumbar spine when lying on it, which will also damage the soft tissues around the lumbar area and thus produce the symptoms of lumbar pain.
