A herniated lumbar disc is not serious if there are no symptoms and does not require special treatment. If the symptoms are more severe and seriously affect your life, it means that it is more serious and you need to seek medical treatment in time. Lumbar disc herniation is caused by changes in the structure of the lumbar spine so that the spinal nerves are compressed. Whether the lumbar disc herniation is serious or not is related to the size of the herniated disc and the compression of the nerves. If the herniated lumbar disc only causes pain in the lumbar region and the pain is mild, and the pressure on the spinal nerves is not obvious, then the herniated lumbar disc is not serious, and it can be treated by changing the lifestyle, physical therapy, oral medication, etc. If the herniated lumbar disc is even prolapsed, then the spinal nerves can be compressed. If the lumbar disc herniation or even prolapse into the spinal canal causes serious compression of the spinal nerves, it will cause severe back pain, leg pain, leg numbness and other symptoms, and even restriction of activities. This is a more serious case of lumbar disc herniation and requires timely surgery to remove the herniated disc and relieve the pressure on the spinal cord and nerve roots. Whether the lumbar disc herniation is serious or not, we need to ask the doctor to make a clear diagnosis and take targeted treatment, and we suggest that the patient should consult the doctor in time and take proper treatment under the doctor’s guidance.
