Physiological curvature change refers to the tilt, straightening or deepening of the curvature of the spine, causing the original physiological curvature to disappear or be deformed, which can be seen in scoliosis, cervical spondylosis, lumbar disc herniation. Symptoms should be timely medical care to clarify the cause of the disease. 1. Lateral spine protrusion: One or several segments of the spine are bent to the side due to neuromuscular atrophy or congenital factors. Patients will have unequal shoulders, asymmetry of the thorax, and folds in one side of the waist. Muscle exercises can be performed, and younger patients can be treated with braces, and surgery can be performed if necessary. 2. Cervical spondylosis: degenerative disease of the intervertebral discs of the cervical spine may lead to cervical spine physiological curve straightening or backward arching, compression of nerve roots, blood vessels and other tissues causing syndromes with symptoms such as stiff neck and back, pain in the upper limbs, numbness in the lower limbs and changes in the physiological curvature of the spine. Patients should avoid prolonged bowing of the head, and if necessary, can use drugs such as diclofenac under the guidance of the doctor. 3. Lumbar disc herniation: caused by the herniated nucleus pulposus of the lumbar disc compressing the surrounding tissues, which will lead to changes in the physiological curvature of the lumbar spine. Patients will have lumbar pain, leg pain, lower limb weakness and deformation of the physiological curvature of the spine. If symptoms such as vertebral pain and numbness in the shoulders and back occur, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease and then give targeted treatment or therapy.
