Patient History
, History of Present Illness (HPI)Thomas Bennett presents with a
20-month history of persistent lower back pain, primarily
localized to the lumbar region (L4-L5). He describes the pain as
a constant, dull ache, rated 5–7/10 on a numeric pain scale,
escalating to 8–9/10 with prolonged standing, heavy lifting, or
extended sitting. The pain occasionally radiates to the right
buttock but does not extend below the knee, distinguishing it
from radicular pain. Thomas reports morning stiffness lasting
15–30 minutes, which improves with light movement, such as
walking or stretching. He denies numbness, tingling, weakness,
bowel or bladder dysfunction, saddle anesthesia, or saddle-area
numbness. Over-the-counter ibuprofen (400 mg, 1–2 times daily
as needed) provides moderate relief (pain reduced to 3–4/10), but
the pain has progressively worsened, significantly impacting his
role as a warehouse supervisor and his ability to engage in
hobbies like fishing and woodworking. He denies recent trauma,
falls, or injuries and reports no systemic symptoms, including
