Why your lower back pain keeps coming back
In short
Most people with recurring lower back pain are stuck in a treatment loop. Here is what is actually happening and how to break the cycle.
Lower back pain is a common reason people see a physiotherapist. Most people treat the flare-up with painkillers, a few days of rest, and maybe a heating pad, and they feel better within a week or two. Then, a few months later, it comes back. The treatment loop repeats. What is often missing is attention to contributing patterns such as movement habits, load, strength, mobility, sleep, stress, and activity levels. The flare-up is just the signal. The contributing factors are often still there.
Why does it keep coming back?
Recurring lower back pain often has multiple contributing factors. Common contributors may include reduced activity in deep stabilising muscles (the multifidus and transversus abdominis), limited hip mobility, and habitual movement patterns that load the spine unevenly. Sitting for long hours in office chairs, or on the floor without back support, can shorten the hip flexors and reduce glute activation. When you go to lift something heavy or twist suddenly, the lower back may take more load than is ideal. A physiotherapy assessment can help identify what is specifically contributing in your case.
Common triggers to recognise
- Long sitting periods: Sitting in one position for long stretches lets the back stiffen and the supporting muscles switch off. There is no single correct sitting time, so take a short movement break and change position when you can. Office workers, drivers, and anyone with a long daily commute are particularly at risk.
- Poor lifting mechanics: Lifting from a bent-back position instead of hinging at the hips places the load directly onto the lumbar joints and discs. Even lifting something light repeatedly in this way adds up over a day.
- Mattress and sleeping position: Sleeping on a very soft mattress that offers no spinal support puts the lower back into an uncontrolled position for 6-8 hours. Side sleepers who let their top knee drop forward also rotate the lumbar spine throughout the night.
- Stress and sleep quality: High stress raises cortisol and increases pain sensitivity. Poor sleep means the body does not recover between episodes. Both make the back more vulnerable to flare-ups from loads that would otherwise cause no problem.
- Rest without rehab: A previous episode that was treated with rest only, and no targeted rehabilitation, leaves the stabilising muscles weaker and the movement pattern unchanged. The next episode is then more likely, often from a smaller trigger than the first time.
Three exercises that help break the cycle
Pelvic tilt
Objective: Activates the deep stabilisers of the lower back and resets neutral spine position.
- 1Lie on your back with knees bent and feet flat on the floor.
- 2Breathe in to prepare.
- 3As you breathe out, gently flatten the small of your back against the floor by tightening your lower abdomen.
- 4Hold for 5 seconds, then release slowly.
- 5Do not hold your breath or brace forcefully.
Bird dog
Objective: Builds coordination between the deep core and the back extensors while keeping the spine still.
- 1Start on hands and knees with a flat back (like a tabletop).
- 2Reach your right arm forward and your left leg back at the same time.
- 3Keep your hips level and avoid rotating.
- 4Hold for 3 seconds, then return to the start.
- 5Repeat on the other side.
Glute bridge
Objective: Strengthens the glutes so they can share the load that currently falls on the lower back.
- 1Lie on your back with knees bent and feet flat, hip-width apart.
- 2Press through your heels and lift your hips until your body forms a straight line from knee to shoulder.
- 3Squeeze your glutes at the top for 2 seconds.
- 4Lower down slowly.
- 5Keep your core gently engaged throughout.
When to see a physiotherapist
If the pain is constant rather than episodic, if it radiates into your leg or comes with numbness or pins and needles, or if these exercises cause a sharp increase in pain, book an appointment. A physiotherapist can assess your movement patterns, identify what is specifically driving your pain, and give you a programme tailored to your spine. Many people with recurring back pain improve over a course of physiotherapy when the underlying movement pattern is addressed, not just the flare-up. Your physiotherapist will set realistic milestones with you.

Recurring lower back pain often has multiple contributing factors. Common contributors may include reduced activity in deep stabilising muscles, limited hip mobility, and habitual movement patterns that load the spine unevenly. Rest addresses the flare-up but not these contributing factors. Without targeted rehabilitation, the next episode may be more likely.
When should I see a physiotherapist for lower back pain?
See a physiotherapist if your pain is constant rather than episodic, if it radiates into your leg, or if it comes with numbness or pins and needles. Also book an appointment if the pain has returned more than twice in the past year. Seek emergency medical care the same day if you have numbness around the groin or back passage, difficulty controlling your bladder or bowel, or new weakness in both legs, as these can signal a serious problem that needs urgent assessment. A physio can identify the specific cause and build a programme around it.
If your back pain has come back more than twice in the past year, a physiotherapy assessment can help identify contributing factors and build a programme around them. Book a physiotherapist on BookPhysio.in.
