If back pain comes with loss of bladder or bowel control, numbness around the groin and buttocks, or rapidly increasing weakness in the legs, go to the emergency department without waiting. Fever, unexplained weight loss, a history of cancer, a significant fall, or night pain that never eases with rest call for a medical assessment within a few days. Without these signs, the vast majority of back pain is not caused by serious disease and can be safely managed with physiotherapy.
Why is most back pain not dangerous?
Back pain is very common and is usually linked to overloaded muscles, joints and ligaments. This kind of "non-specific" back pain generally improves noticeably within the first few weeks. Severe pain does not necessarily mean serious damage.
Red flags are signs that fall outside this general picture and suggest there may be a different underlying problem. They are rare, but they should not be missed.
Urgency at a glance
| Level | Signs | What to do |
|---|---|---|
| Emergency | Unable to pass or hold urine, bowel incontinence, numbness around the groin and buttocks, weakness in both legs or rapidly worsening weakness | Go to the emergency department now |
| Emergency | Sudden, very severe back or abdominal pain with feeling faint or a cold sweat | Go to the emergency department now |
| Within a few days | Fever, unexplained weight loss, history of cancer, pain at night and at rest that does not ease | Medical assessment |
| Within a few days | Pain after a significant fall or accident; sudden pain after a minor strain if you have osteoporosis | Medical assessment, imaging if needed |
| Start with physiotherapy | Back pain that changes with movement and does not affect your general health; pain spreading into the leg without weakness | Physiotherapy assessment |
Emergencies
Cauda equina syndrome
This is severe compression of the nerve roots at the lower end of the spinal canal. Signs include:
- Difficulty passing urine, loss of bladder control or loss of the sensation of needing to go
- Bowel incontinence
- Numbness in the groin, buttocks and inner thighs (the area that touches a bicycle saddle)
- New changes in sexual function
- Pain, numbness or weakness in both legs
It is rare, but hours matter. Delay can lead to permanent damage.
Progressive weakness
Rapidly worsening weakness — such as being unable to lift your foot, or to walk on your toes or heels — needs urgent medical assessment.
When to see a doctor within a few days
- Fever or signs of infection: especially after a recent infection, on immune-suppressing treatment, or with intravenous drug use
- History of cancer: having been treated for cancer in the past
- Unexplained weight loss and general malaise
- Night pain: constant pain that wakes you and does not ease with any change of position
- Trauma: a fall from height or a road accident; for people with osteoporosis, even a minor fall or strain
- Long-term steroid use
- Pain starting for the first time after 50 and behaving unusually
- Morning stiffness: back pain that began at a young age, lasts for hours in the morning, improves with movement and worsens with rest — a rheumatology assessment may be needed
A single sign on its own does not mean serious disease, but it does need a doctor's assessment.
Yellow flags: factors that slow recovery
Some factors are not dangerous but are linked to pain lasting longer:
- Fear of moving, believing that pain means harm
- Long periods of bed rest
- High stress, anxiety or low mood
- Worries about returning to work
Physiotherapy addresses these too; accurate information and gradual movement are an important part of recovery.
What does a physiotherapist do?
At the first session, the physiotherapist screens for red flags and carries out a neurological examination. If a red flag is suspected, you are referred to a doctor. If not, you build a plan together: positions that ease pain, manual therapy, exercise and a return to daily life. We describe what happens in your first physiotherapy session, and for pain spreading into the leg, see our herniated disc article.
Frequently asked questions
Do I need an MRI for every episode of back pain? No. Without red flags, early imaging usually does not change treatment. The decision to scan is made by a doctor based on the examination.
If the pain is very severe, is it dangerous? Not on its own. The accompanying signs above matter more than how intense the pain is.
When can I start physiotherapy? If there are no red flags, from the first days. Early, gradual movement helps more than prolonged rest.
I have numbness in my leg — is that an emergency? Numbness or pain spreading into one leg is not an emergency on its own. Symptoms in both legs, bladder or bowel problems, or rapidly worsening weakness are.
Without red flags, how long will recovery take? For most people, pain eases noticeably within the first few weeks. Pain that has not changed at all after a few weeks, or keeps getting worse, should be reassessed.
