Almost everyone gets back pain at some point. The instinct is to lie down and rest — and that is usually the worst thing you can do. Here is what actually works.
Lower back pain is one of the most common reasons people see a doctor anywhere in the world. Most of it is not serious, most of it needs no scan, and most of it improves within weeks.
But almost everyone gets the first response wrong.
Bed rest is the wrong instinct
When your back hurts, lying still feels like the sensible thing. For decades that was even the standard medical advice.
It turned out to be wrong. People who take to bed with back pain recover more slowly than people who keep gently moving. Muscles weaken quickly, the back stiffens, and the fear of moving makes everything worse.
The current advice is straightforward: stay as active as your pain allows. You may need to avoid heavy lifting or long sitting for a while, but keep walking, keep doing your normal routine, and get moving again as soon as you can. A day or two of taking it easier is fine. A week in bed is harmful.
Most back pain has no single cause
The large majority of back pain is what doctors call non-specific. That is not a fudge — it genuinely means the pain comes from muscles, ligaments and joints working together, with no one structure to blame and nothing that a scan would usefully show.
This is why doctors do not order an MRI for ordinary back pain, and it frustrates people who feel they are being fobbed off. The reason is solid: scans of people with no back pain at all routinely show disc bulges and degeneration. Scanning early leads to findings that were never causing the pain, unnecessary worry, and sometimes surgery that does not help.
Age-related changes on a report are not a sentence. They are as normal as grey hair.
What actually helps
Keep moving. Walking is the single most useful thing for most back pain. Start with short walks and build up.
Heat. A hot water bottle, heat pack or warm shower relaxes the muscle spasm that accompanies most back pain.
Painkillers, sensibly. Simple painkillers can make it possible to keep moving, which is the actual goal. Take them so you can be active, not so you can push through heavy work. Ask your doctor or pharmacist which is suitable for you.
Change position often. Long sitting is hard on the lower back. Get up every half hour. See sitting less at a desk job.
Exercise, once the acute pain has eased. This is the part that prevents it coming back, and it has better evidence behind it than any tablet. Strengthening the core, hips and back reduces both how often back pain returns and how bad it is. See simple strength exercises at home and walking for health.
Sleep in a position that suits you. On your side with a pillow between the knees, or on your back with a pillow under the knees, takes pressure off the lower back. There is no single correct mattress — a medium-firm one suits most people.
Lose weight if you are carrying extra around the middle, which increases the load on your lower back with every step.
How to lift without hurting yourself
- Stand close to the object rather than reaching for it
- Bend your knees and hips, not your back
- Keep the load close to your body
- Do not twist while lifting — turn your feet instead
- If it is heavy or awkward, get help. Nobody is impressed by a slipped disc.
The warning signs that change everything
Most back pain is harmless. A small number of cases are not, and these signs need urgent attention.
Go to hospital immediately if you have:
- Loss of control over your bladder or bowels
- Numbness around the genitals, buttocks or inner thighs — the area that would touch a saddle
- Weakness in both legs, or rapidly worsening weakness in one
These can indicate cauda equina syndrome, where nerves at the base of the spine are compressed. It is a surgical emergency and delay can cause permanent damage. This is not a “see how it goes tomorrow” situation.
See a doctor promptly if you have:
- Back pain after a significant fall or accident
- Back pain with fever, or with unexplained weight loss
- Pain that is severe at night or wakes you from sleep
- New back pain starting after about age 50
- A history of cancer or osteoporosis, or long-term steroid use
- Pain travelling down the leg below the knee with numbness or weakness
- No improvement at all after four to six weeks

Common questions
Do I need an MRI for back pain?
Usually not, and having one too early often does more harm than good. Scans are for people with warning signs, nerve symptoms, injury, or pain that is not improving after several weeks.
Should I use a lumbar belt?
Short-term use during heavy work may help some people. Wearing one all day is not advisable, because the muscles that should be supporting your back stop doing the job and weaken.
Is a hard mattress better for back pain?
Not necessarily. Very hard mattresses suit some people and make others worse. Medium-firm suits most. Comfort and sleeping well matter more than firmness.
Will back pain come back?
It often does, which is exactly why the exercise part matters. People who build and maintain strength have fewer and milder episodes.
