When Radiculopathy Isn't Radiculopathy: A Clinical Series (Pt. 1)
hen Radiculopathy Isn’t Radiculopathy: A Clinical Series

Radicular-like pain of the upper and lower extremities is among the most common presentations in musculoskeletal and spine-related practice. Traditionally, these symptoms are interpreted through a disc-centric and dermatomal framework, often leading clinicians to attribute limb pain, paresthesia or perceived weakness to spinal nerve-root pathology. While this approach is appropriate in cases of true radiculopathy, it frequently falls short when symptoms fail to follow consistent dermatomal patterns or correlate poorly with imaging findings.

Chronic Sciatica: Ending the Relapse Cycle
Chronic Sciatica: Ending the Relapse Cycle

A 46-year-old male presented to our clinic with a seven-year history of recurrent low back pain with sciatica. He reported stiffness and discomfort that worsened with prolonged sitting both at his desk job and during evening television time. The patient had seen multiple chiropractors over the years. In every case, spinal manipulation and other passive treatments would bring gradual symptom relief over 2-3 months. However, within another 3-6 months, the symptoms would return. Frustrated – and now considering a spinal injection and possibly surgery if that failed, he came to our office seeking a different approach.
