Scope

Use for

Primary care back pain triage, conservative management, and imaging appropriateness.

Not for

Establish pain pattern, trauma/cancer/infection risks, function, and neurologic findings; ask specifically about new urinary retention, saddle sensory change, and progressive weakness.
Distinguish nonspecific or radicular pain from suspected serious pathology before selecting conservative treatment.

Treat these as urgent. Escalate early if concern persists or follow-up is unreliable.

Suspected cauda equina syndrome, progressive motor deficit, spinal infection, epidural abscess/hematoma, or significant fracture needs urgent emergency assessment and appropriate imaging.
Suspected malignancy or other serious underlying disease requires prompt investigation; choose urgency from the clinical findings rather than duration of pain alone.

Encourage tolerable activity and self-management, with individualized exercise/physiotherapy when appropriate; avoid prolonged bed rest.
Consider short-term analgesia after renal, GI, cardiovascular, pregnancy, and interaction checks. Use the lowest effective NSAID dose for the shortest duration when appropriate.
Do not routinely image uncomplicated low back pain. Persistence alone is not an indication; image when serious pathology is suspected or results will guide a specific evidence-based intervention.

Agree reassessment based on severity and functional progress; provide immediate-return instructions for new bladder/bowel dysfunction, saddle sensory loss, or weakness.
Persistent disabling radicular symptoms may warrant imaging/specialist review when an intervention is being considered, rather than automatic imaging for every prolonged episode.

Return precautions you can say as written:

“If symptoms get worse, new warning signs appear, or you cannot follow the plan from this visit, seek urgent care now.”

Point to the red flags above that apply to this patient.
Confirm follow-up timing and where to go after hours.
Attach a relevant handout to reinforce the plan.
Document disposition, rationale, unresolved uncertainty, and that precautions were understood.
