As to if a person can feel the difference between the two, it’s unlikely. Worse, many patients can have both as a pain generators, since degenerative disc disease can “fan out” to adjacent tissues. As degeneration occurs, the change in bio-mechanics stress other joints and ligaments -- especially the facets (Z joints).
That’s where a good diagnostic approach can help, whether surgical, natural, or both. I used both approaches.
