People often mistake, if not interchange bulging disc with herniated disc. However, there is a huge difference between the two. The latter refers to a crack or rupture on the outer layer of the spinal disc. This crack causes the spinal fluid to slip out of the disc and affect the surrounding areas of the damaged disc, including the nerves, which results to pain. Bulging disc in back on the other hand, is simply a bulge on the outside of the disc, no cracks or rupture. However, it can cause mild discomfort, tingling sensation, weakness and numbness that can go down to the shoulders, arms and fingers. In some cases, it may not cause pain at all. But when left untreated, it develops to herniated disc.
