Very true. I understand the use of “non-specific” low back pain as imaging is often unclear of the source of the pain (facet, ligament, or muscle). If degeneration and herniations are inconsistent, with imaging studies showing many people have no pain with pathology on MRI and vice versa. Even so, from a research perspective, making distinctions can be helpful as the variables contributing to the development differ (age, activity, trauma, cancer, etc.). And even if we classify it as non-specific, individual treatment is always needed.
