Treatment chronology
Acute lumbar strain with paraspinal tenderness at L4–L5; X-ray negative for fracture. Prescribed cyclobenzaprine, discharged with activity restrictions and ortho referral.
Positive straight-leg-raise on the right; decreased lumbar range of motion. Ordered lumbar MRI to rule out disc involvement.
4 mm disc herniation at L4–L5 with right-sided neural-foraminal narrowing and nerve-root impingement. Mild facet arthropathy noted.
Diagnosis: lumbar radiculopathy secondary to L4–L5 herniation. Recommended a course of physical therapy and a lumbar epidural steroid injection.
PT evaluation and start of therapeutic exercise; began an 18-session course addressing lumbar stabilization and radicular symptoms.
Lumbar epidural steroid injection at L4–L5 under fluoroscopy. Tolerated well; partial symptom relief reported at follow-up.
Completed 18 sessions. Discharge note documents residual radicular symptoms with activity and a recommendation for a home exercise program.
