As your mother is 65 years old surgery is not advisable. Moreover it is not 100% gurenteed that the surgery will solve the problem. Bulging intervertebral discs are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root. With aging, the outer fibrous portion of intervertebral discs is weakened. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. Many people have bulging discs without realizing it. As long as the bulging area does not press upon surrounding neural tissues, no symptoms occur.
