Back pain – why rest is usually the wrong answer
Most back pain has no serious cause and improves with movement rather than bed rest. What helps, what does not, and the red flags that change everything.
Most back pain has no dangerous cause
The overwhelming majority of back pain is what clinicians call non-specific: no single damaged structure, no serious disease, and no scan finding that reliably explains it. That sounds dismissive and is actually good news, because this kind improves.
Severity of pain is a poor guide to seriousness. A muscle spasm can be agonising and harmless; a serious cause can start mildly. What identifies the dangerous minority is the pattern and the associated symptoms, not the intensity.
Movement beats rest
Bed rest was standard advice for decades and has been reversed. More than a day or two of lying down makes back pain worse and recovery slower — muscles weaken, stiffness increases, and confidence drops.
- Keep moving within what the pain allows. Gentle walking is ideal.
- Stay at work or return early if you can, adjusting tasks rather than stopping entirely.
- Use pain relief so you can move, rather than waiting to be pain-free before moving.
- Heat helps most people for muscle spasm; some prefer cold in the first day or two.
- Keep sleeping normally, in whatever position is comfortable.
- Build back to normal activity over days to weeks rather than waiting for zero pain.
For relief, so you can keep moving:
Paracetamol — Panado, Painamol, Tylenol, Pacimol
Mild to moderate pain; fever
Ibuprofen — Nurofen, Brufen, Advil, Ibupain
Mild to moderate pain; inflammation; fever; dysmenorrhoea
Diclofenac — Voltaren, Cataflam, Olfen, Panamor
Moderate pain; musculoskeletal and post-operative pain; inflammation
Methyl Salicylate + Menthol (Topical Counterirritant) — Deep Heat, Deep Heat Rub, Tiger Balm, Mentholatum
Muscular aches; joint stiffness; sports injuries; backache; sprains
Red flags
Preventing the next episode
- Strength and general fitness protect the back better than any lifting technique — the evidence for exercise is stronger than for back belts or ergonomic chairs.
- Lift with the legs, keep the load close, and turn with the feet rather than twisting the spine.
- Break up long periods of sitting; changing position often matters more than the perfect position.
- Stop smoking — it is associated with more back pain and slower healing.
- Manage stress and sleep. Both measurably affect how much pain is felt.
Common questions
- Should I get a scan?
- Usually not, and early scanning for ordinary back pain is associated with worse outcomes. Most adults have disc bulges and wear on imaging with no pain at all, so a scan often finds something incidental that then gets blamed and worried about. Scans are for red flags and for cases not improving.
- Is a firm mattress better?
- A medium-firm mattress suits most people, but the evidence is weak and comfort is the better guide. Replacing a mattress is not a treatment for back pain.
- Is it safe to exercise with back pain?
- Generally yes, and it is one of the more effective things you can do. Start gently and build up. A physiotherapist can guide it, particularly if pain recurs or has lasted a while.
