Nonspecific. Believe it or not, scoliosis does not cause pain for most patients - unless the scoliosis is very severe. Similarly, a disk bulge is often of no consequence, and is simply a normal finding as we age. See a physician (consider seeing a neurologist since you have numbness) for further evaluation.
