If the back is sore and back pain after long sleep, the following causes are common: 1. The muscles of the back and lumbar region are continuously compressed: the level of tissue metabolism of the muscles is significantly reduced, and the accumulation of acidic metabolites can cause back pain and back pain. 2. The physiological curvature of the lumbar spine is changed: the patient will have increased stress in the lumbar spine and degeneration of the lumbar intervertebral disc and other structures, resulting in clinical symptoms of back pain and back pain. Therefore, sleep time should be properly controlled to avoid prolonged sleep causing the above clinical symptoms. At the same time, if there are symptoms of lumbar pain and back pain, timely treatment, such as massage, acupuncture, physiotherapy and exercise of the muscles of the lumbar back, must be carried out to avoid continuous attacks of symptoms, which may affect the patient’s normal life, work and sports.
