Week of Study Week 9
Chief Complaint (Patient’s Own Words)
“Doc, my lower back has been hurting for about three months now, but the last two weeks it’s gotten
much worse. I can’t do my morning walks anymore, and it hurts to stand up from a chair. My husband
says I look like I’ve aged ten years overnight.”
Reason for Encounter
The patient presents to the outpatient primary care clinic for evaluation of persistent low back pain,
reportedly progressive over the preceding three months with significant exacerbation in the last two
weeks. She reports functional decline in activities of daily living and mobility limitations.
Source and Reliability
,The patient is the sole historian; she is alert, oriented, and conversant. No family member or caregiver is
present at the encounter. Speech is clear with appropriate affect. She appears mildly distressed but
cooperative. Reliability of the history is deemed high.
SECTION 2: SUBJECTIVE DATA (History of Present Illness)
Overview
Low back pain is one of the most common complaints encountered in primary care and among older
adults. According to population-based studies, prevalence estimates range from 6% to 84% depending
on the definition and population evaluated; one study of 70-year-olds found 44% reporting back pain,
while 58% of 77-year-olds experienced similar complaints. People aged 60 years and over are more likely
to experience incapacitating and persistent episodes of low back pain than younger people.
Onset
• Timeline: Three-month duration of low back pain, initially intermittent and mild.
• Acute worsening: Significant progression over the past two weeks.
• Triggers: No identifiable inciting event or trauma reported. “I just woke up one morning and it
was there. It got worse over time.”
• Pattern: Insidious onset with slow progression, then subacute exacerbation.
Location
• Primary site: Lower lumbar region, centered over the midline and paravertebral musculature
(L4–S1 distribution).
• Radiation: No radiation into buttocks, thighs, or lower extremities. No paresthesias or
dysesthesias.
• “I can point to exactly where it hurts — right here in the center of my low back. It does not go
down my legs.”
Quality
Patients describe chronic back pain from the subpopulation of older adults as comprising various pain
syndromes originating from vertebral bodies, joints, muscles, and other soft tissues.
• Descriptors: “Dull ache” most of the time, with intermittent “sharp” episodes when moving in
certain positions.
• Character: Mechanical in nature (worse with activity, better with rest and recumbency).
Severity
• Current severity (on 0–10 numeric pain rating scale): 6/10 at rest; 8/10 with activity (standing
up from seated position, bending forward, walking > 10 minutes).
, • Best in last week: 3/10 (after resting supine for several hours).
• Worst in last week: 9/10 (after attempting morning walk).
Timing
• Diurnal variation: Worse in the morning upon rising (gelling phenomenon of approximately 15–
20 minutes), then improves slightly with gentle movement, then worsens again with sustained
activity.
• Nocturnal pain: Denies being awakened from sleep by pain; able to find comfortable position
supine with knees slightly flexed.
• Duration of current exacerbation: Two weeks.
Context / Associated Symptoms
• Constitutional symptoms: Denies fever, chills, night sweats, or unexplained weight loss. Reports
fatigue secondary to poor sleep quality due to positioning difficulty.
• Bowel/bladder function: Denies urinary or fecal incontinence, retention, or saddle anesthesia.
• Neurologic symptoms: Denies weakness in lower extremities, numbness, tingling, or gait
instability. Patient ambulates independently but with some hesitation.
• Fall risk awareness: Reports no falls in the past year but states she feels “unsteady” when pain
increases suddenly. “I hold onto the wall when I first stand up.”
Aggravating Factors
Activity Effect on Pain
Prolonged sitting (>30 minutes) Significant worsening
Standing up from seated position Sharp, transient increase (7–8/10)
Walking >10 minutes Gradual increase (5–8/10)
Bending forward (e.g., to pick up objects) Moderate worsening
Lumbar extension (leaning back) Moderate worsening
Prolonged standing Significant worsening
