A lumbar bulging disc means that the nucleus pulposus of the intervertebral disc between two vertebrae loses its ability to creep, and as the nucleus pulposus loses moisture with age, the annulus fibrosus develops some degenerative fissures, and the disc will bulge out in all directions. Early lumbar bulging discs usually do not compress the nerves and do not cause radiating pain in the legs, but they often cause lumbar pain, lumbar muscle tension, scoliosis and other symptoms. 1. Lumbar pain: the displacement of the nucleus pulposus of lumbar disc bulge may form the instability of the spinal column, thus causing pain in the middle of the lumbar region, especially in the middle of the lumbosacral region, the pain is mainly soreness and swelling, and the pain is obviously aggravated when bending over. 2. Muscle tension in the lumbar region: In the early stage, the muscles will be stiff, affecting the ligaments around the vertebral joints, resulting in a sense of stagnation or difficulty in movement. 3. Scoliosis: Nucleus pulposus of lumbar intervertebral disc bulge can be observed in patients with obvious changes in the shape of the spine, scoliosis, lumbar vertebrae physiological anterior convexity is reduced or disappeared, and in severe cases, the spine can be drawn back. When lumbar disc bulging, it is recommended to consult a doctor in time, and follow the doctor’s instructions for treatment after diagnosis. Avoid prolonged sitting, reduce lumbar pressure, strengthen the lumbar back muscle training, to prevent lumbar disc herniation and other serious conditions.
