Studies have demonstrated that approximately 33% of the human populations have Bulging Discs in their spines with no symptoms at all. The most common symptoms are dependent on what level the disc bulge is. For example, in the neck, a disc bulge can cause, pain, electric shocks, numbness and tingling in the shoulders, arms and hands. In the low back, one could experience those same symptoms in their hips, legs and feet. Most people know the term “sciatica” which is typically caused by a disc bulge on the sciatic nerve in the low back and leg.
