Acute Low Back Pain with Red Flags in a 58-Year-Old Driver
A 58-year-old taxi driver attends with 10 days of low back pain after lifting a suitcase. Pain is 7/10, worse at night and unrelieved by rest. He has unintentional weight loss of 6 kg over three months, a history of smoking, and no prior episode of back pain. Straight-leg raise is 40 degrees on the right with hamstring tightness but no dermatomal sensory loss; reflexes are symmetric; he has no bladder or bowel change and no saddle anaesthesia. He drives 10 hours a day and asks for 'strong painkillers and a sick note' so he can keep working. He has no regular doctor and has not had blood tests.
1. What is your immediate clinical priority, and how does it change your management plan?

The priority is not the mechanical back pain but the red flags: age over 50 with a new episode, unintentional weight loss, night pain unrelieved by rest, and a smoking history. Together these raise concern for serious pathology, particularly malignancy or infection, and justify urgent medical referral rather than a course of physiotherapy. I would not treat this as simple mechanical pain.
I would take a focused history (fever, night sweats, past cancers, steroid use, intravenous drug use, recent infection) and perform a neurological screen. I would arrange same-day or next-day medical review with bloods including inflammatory markers and consider imaging as directed by the physician. I would explain clearly that the painkillers and sick note are secondary to ruling out a serious cause, and that I am not withholding help but escalating it. I would document the red flags, the referral, and the safety-net advice: return immediately for bladder or bowel dysfunction, saddle numbness, progressive weakness, or fever.
2. Assuming serious pathology is excluded, how would you address his request to keep driving 10 hours a day?

Once cleared, I would negotiate a graded return rather than simply signing him off or endorsing 10 hours unchanged. Prolonged sitting is a provoker, not a cause, but 10 hours with no breaks will hamper recovery and is a safety issue if pain distracts him while driving.
Plan: shorter shifts initially (for example 5-6 hours) for 1-2 weeks, with a break every 45-60 minutes to stand and walk for 2-3 minutes; lumbar support adjusted so the pelvis is neutral; seat slightly reclined and close enough that he does not slump; simple analgesia timed before shifts rather than after pain peaks. Add daily walking and a home exercise programme (direction-preference movements, hip hinge training, graded lifting practice with a suitcase). Review at one week, and use a pain-monitoring rule: pain should settle within 24 hours of activity. I would issue a fit note with amended duties rather than a blanket sick note, since complete rest is likely to worsen his outcome and his livelihood.
