Your MRI came back normal, and your back still hurts. You are not alone. IQWiG, Germany's health information institute, says that for over 85 in 100 people with back pain no clear cause can be found. In Sam's symptom diary you log lower back pain per day as mild, moderate or severe. The monthly report you create yourself (it has requirements, see below) shows your symptom days on a calendar. Below: what a normal report means, what happens next, what to log and when another check is needed.

For when back pain counts as chronic and why a scan is rarely the first step, see when is back pain chronic? This post starts after the scan. What Sam keeps for this condition is on the chronic low back pain page.

What does a normal MRI report mean?

When back pain has lasted for weeks, a scan can help rule out a specific cause. That is how the German national patient guideline puts it. A specific cause is one that needs its own care, such as a fracture, an infection or, very rarely, cancer. A normal report means the scan found nothing of that kind in the area scanned.

Your report may still mention wear and tear or age-related changes. Ask what that means for you. X-rays and MRI scans often show such changes, the guideline says, and it is usually unclear whether they cause the pain. People without any back pain have them too.

A normal result also has limits. It covers only the scan you had, on the day you had it. It does not say that your back is healthy. If new symptoms appear later, an old scan cannot answer them. Whatever words your report uses, ask your doctor to explain them.

The same goes for an X-ray. A standard X-ray is used mainly to check bones, for example for a fracture, says the NHS. Whether an MRI is needed after that is for your doctor to decide.

What is non-specific low back pain?

Non-specific low back pain is the name for back pain with no sign of a dangerous cause that needs specific measures. Specific back pain is the term when a cause can be found. The German national patient guideline puts non-specific pain at about 85 to 90 in 100 people with low back pain. Its 2017 edition is no longer valid, according to the guideline programme's topic page.

Because non-specific low back pain has no known structural cause, care focuses on reducing the pain and its consequences, a 2017 Lancet review explains.

Non-specific describes what was not found. It says nothing about how strong the pain is. IQWiG, Germany's health information institute, describes chronic low back pain as very varied. It can be mild but always there, or strong and lasting for a long time. German patient information notes that it can be a heavy burden and limit daily life considerably. Pain without a finding is real pain.

Why does it hurt if the scan shows nothing?

Many structures sit close together in the back: muscles, fascia, ligaments and the joints of the spine. Because several causes often work together, even an MRI usually cannot give a firm answer, IQWiG says. It lists factors that can set off non-specific back pain, including:

  • Too little movement and long periods of sitting still.
  • One-sided or unusually heavy physical work.
  • Tense muscles.
  • Mental strain such as stress at work, money worries or family worries.
  • Marked anxiety or self-doubt, and conditions such as depression.
  • Changes in how the central nervous system processes pain, which can cause chronic pain.
  • A family tendency.

That mental strain can play a part does not mean the pain is imagined.

The 2018 Lancet paper points the same way. It reports increasing evidence that central pain-modulating mechanisms and pain cognitions have important roles in the development of persistent, disabling back pain. Pain cognitions means how a person thinks about their pain. The paper also names psychological distress among the factors that raise that risk.

Some causes are hard to see on an MRI, and some sit outside the spine. IQWiG names facet joint syndrome, an irritation of nerve endings caused by age-related changes in the spinal joints. It is very hard to pin down, and an MRI is not informative for it. Occasionally back pain comes from somewhere else entirely, such as kidney stones, an inflamed pancreas or gallbladder, endometriosis or shingles. Whether any of this applies to you is for your doctor to work out through questions and an examination. A diary cannot settle it. The German patient information also notes that with non-specific low back pain the cause does not have to be found. Searching for an explanation all the time can itself affect the pain.

What happens after a normal scan?

A normal scan does not end your care. For pain that lasts for weeks despite care, the German patient guideline (2017 edition, no longer valid) and its patient information describe these steps:

  • Psychological or work problems can help keep back pain going, so your doctor should ask about strain in your private life and at work. After four weeks of pain despite care, your doctor should check psychological strain on purpose, with a questionnaire or a structured conversation.
  • A scan should not be repeated unless the symptoms change markedly.
  • Several specialists should assess you and plan your care together, for example from pain medicine, psychology or psychiatry, and physiotherapy. This applies if severe, limiting pain lasts more than twelve weeks despite care. It also applies after six weeks if psychological or work-related strain comes on top, and if chronic pain gets worse.

You are allowed to ask. The patient guideline suggests asking your doctor to explain medical terms and asking again if anything is still unclear. Before a test, it suggests asking how reliable the result is. After a normal MRI, you could ask:

  • What do the words in my report mean?
  • Which causes are now less likely, and which would the scan not show?
  • What happens next with my care, and when do we review it?
  • Which changes should bring me back sooner?

Left the appointment feeling dismissed? When your doctor does not take your symptoms seriously covers how to prepare the next conversation. How to get a copy of your report is in the doctor appointment checklist for a chronic condition.

What should you log once the scan is back?

After the scan, change is what matters most. NICE asks clinicians to think about other causes at every review of low back pain. That applies particularly when symptoms are new or have changed. The German guideline says a scan should only be repeated if symptoms change markedly. A log that starts on the day of the scan helps you tell your practice what has changed since:

  • The date and type of scan, what the report said, and how you were that week. This is your starting point.
  • New or changed symptoms, each with a date: pain spreading into a leg or past the knee, numbness, tingling, weakness, pain at night or at rest.
  • How many days a week your back hurts, and how much, on a scale you always use the same way.
  • What you can no longer do at home or at work, or can do again.
  • A word on sleep, stress and mood.
  • Any care added since the scan, such as physiotherapy or a medicine from your doctor, and whether anything changed afterwards.
  • Your questions for the next appointment.

An invented example, not a benchmark: "Lumbar MRI on 3 March, normal. Back then pain on five days out of seven, mostly 4/10. Since 14 April also a pulling pain on the left, down past the knee, three days a week." The second part is a change to get checked by a doctor.

Some things belong with a doctor, not only in the log. For bladder or bowel problems, call your emergency number. For new numbness or growing weakness in one leg, get medical help straight away. The list of signs is in the section on symptoms that need medical help. A log does not lead to a cause or a new scan by itself. It gives the appointment something concrete instead of "much the same". Whether paper or an app suits you better is covered in symptom diary: paper template or app?

In Sam's symptom diary you log lower back pain per day as mild, moderate or severe. For numbness or tingling and for muscle weakness, you can tap a coarse body region, such as the left thigh. Each symptom gets one entry per day, with no time of day, no note and no 0-to-10 scale. So the scan date, the report and where the pain spreads stay on paper. Sam gives no medical assessment of your entries.

You create the monthly report for the previous month yourself. The linked page also describes the doctor report. That exists only in the diaries of certain conditions, not for back pain. The PDF shows your symptom days on a calendar, your five most logged symptoms, and pages on activity, sleep and stress. It needs notifications allowed, Apple Health access and an answer to the chronic-condition question. From the second report on, log how you felt on at least 15 of the last 30 days: good, a bit off or sick. Symptom entries do not count toward that.

When is another check or scan needed?

Whether you are examined again, or scanned again, is your doctor's decision. The sources set out a frame:

  • The German patient guideline (2017 edition, no longer valid) says a new scan should follow only if symptoms change markedly.
  • IQWiG says further tests are sometimes recommended if symptoms have not eased after weeks or are getting worse.
  • The NHS says to see a GP if back pain has not improved after a few weeks. The same goes if it stops your day-to-day activities or worries you.

If the pain gets worse or new symptoms appear, contact your practice earlier. For the symptoms in the next section, do not wait for an appointment.

Which symptoms need medical help even after a normal MRI?

An earlier normal scan changes nothing about these symptoms. The groups follow the NHS, IQWiG, the German patient guideline (table 2; 2017 edition, no longer valid) and the German patient information.

Call your local emergency number (112 in the EU, 999 in the UK, 911 in the US) or go to an emergency department if back pain comes with any of these:

  • Pain, tingling, weakness or numbness in both legs.
  • Numbness in your buttocks or around your genitals or anus.
  • Changes in your bladder or bowels, such as difficulty peeing, or losing control of your bladder or bowels.
  • Changes in how your penis or vagina feels during sex, not being able to get or keep an erection, or not being able to orgasm.
  • Chest pain.
  • Pain that started after a serious accident, such as a car accident.

Do not drive yourself. Ask someone to drive you or call an ambulance.

Get medical help straight away, without waiting for your next appointment, for any of these. In the UK that means an urgent GP appointment or NHS 111. Elsewhere, ask for a same-day appointment or your local out-of-hours service.

  • Signs of paralysis, severe symptoms, new numbness or growing weakness in one leg.
  • A fever, chills, night sweats, or feeling hot, cold, shivery or generally unwell.
  • Severe pain that starts suddenly or gets worse quickly.

See a GP or your doctor about any of these:

  • Weight loss without trying, loss of appetite or a general feeling of physical weakness.
  • A history of cancer.
  • Severe pain at night or at rest.
  • Pain that gets worse at night or when you lie on your back, or that does not ease with rest.
  • Pain after a fall or, with osteoporosis, after heavy lifting or an awkward twist of the spine.
  • Pain spreading down a leg, especially past the knee or into the foot, also with numbness, tingling or weakness.
  • Several signs of inflammatory back pain together: pain lasting more than twelve weeks, a gradual start, morning stiffness that eases with movement and gets worse with rest.
  • Back pain together with psoriasis, inflammatory bowel disease, joint or tendon inflammation or inflammation of the middle layer of the eye.
  • A lump or swelling in your back, or your back has changed shape.
  • Pain that is worse when sneezing, coughing or pooing.
  • Pain between the shoulder blades rather than in the lower back.
  • Back pain that does not improve after a few weeks at home, stops your day-to-day activities, or leaves you worried or struggling to cope.

With the first two groups, do not wait for it to pass. For the third group too, a diary entry does not replace the check by a doctor.

Log the weeks after your scan in Sam and create a monthly report

You arrive with counted symptom days instead of "much the same", without rebuilding the weeks since the scan from memory.

  • Instead of a notebook left at home: you log lower back pain on your phone, per day, as mild, moderate or severe.
  • Instead of a second app for steps: steps and exercise minutes from Apple Health are in the same app as a trend.
  • Instead of a tally sheet: you create the monthly report yourself; the PDF shows your symptom days on a calendar and your five most logged symptoms.

The symptom diary keeps no scan date, 0-to-10 scale, times of day or notes, and the report has the requirements listed above. More on the chronic low back pain page.

Frequently Asked Questions

My MRI is normal but my back still hurts. What does that mean?+

It means the scan showed nothing that points to a specific cause, such as a fracture or an infection, in the area scanned. That is common: IQWiG, Germany's health information institute, says that for over 85 in 100 people with back pain no clear cause can be found. A normal scan does not mean the pain is not real. It also only covers the scan you had, on the day you had it.

What is non-specific low back pain?+

It is low back pain with no sign of a dangerous cause that needs specific measures. The German national patient guideline (2017 edition, no longer valid) puts it at about 85 to 90 in 100 people with low back pain. Non-specific describes what was not found. It says nothing about how strong the pain is or how much it limits your day.

Is back pain real if the MRI shows nothing?+

Yes. Back pain often has several causes that work together, and a scan rarely pins them down, says Germany's health information institute IQWiG. It lists factors such as tense muscles, little movement, mental strain such as stress or anxiety, and changes in how the central nervous system processes pain. German patient information on chronic low back pain notes that it can be a heavy burden and limit daily life considerably.

What should I log after a normal scan?+

Write down the date of the scan, what the report said and how you were at the time. After that, focus on change, with dates: pain spreading into a leg, numbness, tingling, weakness, pain at night or at rest, how many days a week it hurts, what you can no longer do and any new care since the scan. Bladder or bowel problems are an emergency: call your local emergency number. New numbness or growing weakness in one leg needs medical help straight away. The other signs are in the last question.

Will the MRI be repeated if the pain does not go away?+

Not automatically. The German patient guideline says a scan should not be repeated unless the symptoms change markedly. NICE asks clinicians to think about other causes whenever they review someone, particularly if symptoms are new or have changed. Whether you need another check or scan is your doctor's call. If the pain gets worse or new symptoms appear, contact your practice earlier. For the signs in the last answer, do not wait for an appointment.

Is a normal X-ray the same as a normal MRI?+

Not quite. A standard X-ray is used mainly to check bones, for example for a fracture, says the NHS. A normal result only covers the test that was done. Whether an MRI is needed after an X-ray is for your doctor to decide, for example if limiting pain lasts for weeks despite care or there are signs of a serious cause.

Which symptoms need medical help even after a normal MRI?+

Call your local emergency number or go to an emergency department for pain, tingling, weakness or numbness in both legs, numbness in the buttocks or around the genitals or anus, difficulty peeing or loss of bladder or bowel control, changes in how your penis or vagina feels during sex, erection problems or not being able to orgasm, chest pain, or pain after a serious accident. Get medical help straight away, without waiting for your next appointment (in the UK, an urgent GP appointment or NHS 111; elsewhere, a same-day or urgent appointment with your doctor or your local out-of-hours service), for signs of paralysis, severe symptoms, new numbness or growing weakness in one leg, a fever, chills, night sweats or feeling generally unwell, or severe pain that starts suddenly or gets worse quickly. See a doctor about weight loss without trying, loss of appetite or a general feeling of physical weakness, a history of cancer, severe pain at night or at rest, pain that gets worse at night or when you lie on your back or does not ease with rest, pain after a fall or, with osteoporosis, after heavy lifting or an awkward twist of the spine, pain spreading down a leg, especially past the knee or into the foot, also with numbness, tingling or weakness, several signs of inflammatory back pain together (pain lasting more than twelve weeks, a gradual start, morning stiffness that eases with movement and gets worse with rest), back pain together with psoriasis, inflammatory bowel disease, joint or tendon inflammation or inflammation of the middle layer of the eye, a lump, swelling or change of shape in your back, pain that is worse when sneezing, coughing or pooing, pain between the shoulder blades, and back pain that does not improve after a few weeks at home, stops your day-to-day activities, or leaves you worried or struggling to cope. An earlier normal MRI does not change any of this.
