How Long Does Back Pain Last? When to See a Physiotherapist
Most back pain resolves on its own within 6–12 weeks. But 'most' isn't 'all' — and if your back pain has been going on for longer than that, or if it's severe enough to be affecting your daily life, waiting it out may not be the right approach. Here's what you need to know about back pain timelines and when physiotherapy is the right next step.
Acute Back Pain: The First 6 Weeks
Acute back pain — pain that has come on suddenly, often after a specific incident like lifting or twisting — typically improves significantly within 6 weeks. During this period, staying as active as possible (within the limits of your pain) is generally better than rest. Avoid bed rest, keep moving gently, and use over-the-counter pain relief if needed. If your pain is severe, affecting your sleep, or not improving after 2–3 weeks, physiotherapy can significantly accelerate your recovery.
Subacute Back Pain: 6–12 Weeks
If your back pain has been going on for 6–12 weeks without significant improvement, this is called subacute back pain. At this stage, physiotherapy is strongly recommended. Without proper assessment and treatment, subacute back pain has a significant risk of becoming chronic — and chronic back pain is much harder to treat than acute or subacute pain. Don't wait.
Chronic Back Pain: More Than 12 Weeks
Chronic back pain — pain lasting more than 12 weeks — affects a significant proportion of the population and is one of the leading causes of disability in the UK. It doesn't mean your back is permanently damaged. It means the pain system has become sensitised, and recovery requires a different approach — one that addresses both the physical and psychological aspects of persistent pain. Physiotherapy remains the most effective treatment for chronic back pain.
Warning Signs That Need Urgent Attention
Most back pain is not dangerous, but there are warning signs that require urgent medical attention: loss of bladder or bowel control, numbness or tingling in the groin or inner thighs (saddle anaesthesia), severe pain that is constant and not affected by position, back pain with unexplained weight loss or fever, or back pain following a significant trauma. If you have any of these symptoms, seek emergency medical help immediately.
When Physiotherapy Makes the Biggest Difference
Physiotherapy is most effective when started early — in the acute or subacute phase. But it can make a significant difference at any stage, including for chronic back pain. A thorough physiotherapy assessment identifies the specific factors driving your pain and creates a targeted treatment plan — which is far more effective than generic advice or exercises found online.
If your back pain has been going on for more than 2–3 weeks without improvement, or if it's severe enough to be affecting your daily life, physiotherapy is the right next step.
