Low back pain: what to do in the first weeks
Movement heals faster than bed rest
Dr. Marc Lefèvre
Rheumatologist
In simple terms
Most episodes improve within six weeks, and imaging early usually does more harm than good.
The reassuring reality
The great majority of low back pain is non-specific: no dangerous cause, no nerve damage, and no permanent injury. It hurts a lot, and it still gets better. Around 90% of episodes settle substantially within six weeks.
What to do
- Keep moving within tolerable limits; prolonged bed rest slows recovery.
- Use heat, and paracetamol or a short course of anti-inflammatories if suitable for you.
- Return to normal activity gradually rather than waiting to be pain-free.
- Start strengthening and general exercise once the acute phase eases; it is the best prevention of recurrence.
Why an early scan is usually unhelpful
Discs bulge and shrink in most pain-free adults over 40. Finding those normal age changes on an MRI often increases worry and leads to unnecessary procedures without improving outcomes.
Red flags that need urgent care
Loss of bladder or bowel control, numbness in the saddle area, progressive leg weakness, fever with back pain, pain after a significant fall, or a history of cancer. These are the situations where imaging is needed quickly.
