It is impossible to determine exactly how long it takes for a lumbar disc to bulge to the point of nerve compression. This is because this evolution can vary very much from patient to patient. Some patients may remain undeveloped for life or even get better, while others quickly develop a herniated lumbar disc that presses on the nerve. Lumbar disc bulge means that the lumbar disc has degenerated. If the degree of bulge is mild, there is no pressure on the nerves, and only the symptom of lumbar pain occurs; if the condition continues to develop, it can lead to herniation of the disc, prolapse of the nucleus pulposus, and freeing of the nucleus pulposus, etc., which can compress the spinal cord and the nerve roots. If there is no radiating pain in the legs of patients with lumbar bulging disc, it means that the nerve root is not compressed, and the condition can be corrected and prevented by changing bad habits and exercising the lumbar back muscles, etc. The condition of some of the patients can be maintained for many years without any development, and the condition may even get better. If you do not actively protect your lumbar spine in your daily life, often over-bending and weight-bearing, or due to trauma or degeneration of the lumbar spine, you will quickly develop lumbar disc herniation, with symptoms of nerve compression, such as radiating pain and numbness from the buttocks to the calves. It is recommended that patients with lumbar bulging discs should consult the hospital in time, improve the examination, make a clear diagnosis, and actively carry out treatment and preventive health care under the guidance of the doctor to slow down the development of the condition.
