Lower Back Pain: What’s Going On and What You Can Do About It

If your lower back is sore when you get out of bed, aches by the end of the workday, or suddenly “locks” when you bend down, you are far from alone. Lower back pain is one of the most common reasons people miss work, avoid hobbies, or finally book an appointment with a physio. It can make simple things – tying your shoes, lifting your kids, or sitting through a meeting – feel surprisingly hard.

This post is for you if you live with back pain, and also for the physios who support you. We’ll keep things simple and practical, but accurate enough that your clinician will happily nod along.

What Is Lower Back Pain?

Your lower back (the lumbar spine) is the strong, flexible base of your spine. Picture a short stack of sturdy building blocks (the vertebrae) with soft cushions in between them (the discs). Muscles, ligaments, and tendons wrap around this stack like guy ropes and cables, helping you bend, twist, and stay upright.

Lower back pain simply means pain, stiffness, or discomfort in this area, roughly between your lower ribs and the top of your buttocks. The pain can feel:

• Sharp or “catching” pain when you move a certain way
• Dull and aching, especially after sitting or standing too long
• Stiff, like your back is rusty first thing in the morning
• Sometimes spreading into your hips, buttocks, or down one leg

Most of the time, lower back pain is mechanical – it comes from how the joints, discs, muscles, and nerves are moving and loading, not from something serious or dangerous. It can be very painful and disruptive, but the good news is that it is usually treatable and often improves with the right plan.

Common Causes of Lower Back Pain

Poor Posture and Prolonged Sitting

Hours at a desk, on the sofa, or scrolling on your phone can make your lower back complain. When you slump or lean for long periods, some joints and soft tissues take more strain while others switch off and get weak.

It’s less about “perfect posture” and more about staying in one position too long. Your back likes variety: sit, stand, walk, shift, repeat.

Muscle Strain and Overuse

Lifting a heavy box with a twist, gardening all weekend, or suddenly doing more at the gym can overload muscles and tendons in your lower back. They respond like any other tissue that has been asked to do too much, too soon: they get irritated, tight, and sore.

This type of pain often feels worse with certain movements but usually settles well with time, gentle movement, and a gradual return to activity.

Disc Problems: Bulging or Herniated Discs

Remember those cushions between the vertebrae? Each disc has a softer centre and a tougher outer ring, a bit like a jam doughnut. With repeated loading or sometimes a sudden force, the disc can bulge slightly or, in some cases, the softer centre can push further out.

When a disc bulge or herniation irritates a nearby nerve, you might feel:

• Shooting pain down the leg (often called sciatica)
• Numbness, tingling, or “pins and needles”
• Weakness in part of the leg or foot

Even then, discs can heal and settle. Many people with disc changes on scans have no pain at all. What matters most is how your back behaves, not what the MRI picture shows.

Sedentary Lifestyle and Weak Core Muscles

Your deep trunk muscles act like a support team for your spine. If you rarely walk, lift, or move in different directions, this support team gets deconditioned. Then everyday loads – carrying shopping, lifting a toddler, or walking uphill – can feel like too much.

Over time, this can show up as repeated bouts of “my back just goes every few months”. The fix is rarely total rest; it’s usually progressive strengthening and more movement.

Stress and Poor Sleep

Stress does not live only in your head. When you’re under pressure, your muscles often stay slightly tense, your breathing changes, and your nervous system is on high alert. Pain signals can feel louder and more intense.

Lack of sleep adds another layer. Your body repairs tissue and calms inflammation while you sleep. When sleep is short or broken, pain is harder to switch off. That’s why a stressed, tired person often feels more sore, even if their scan has not changed at all.

Age-Related Wear and Tear

As we age, the discs between our vertebrae naturally lose some height and moisture. Joints can become a bit bumpier around the edges. This is often called “degenerative change” on a scan report, which can sound scary, but it is basically the spine version of grey hair and wrinkles.

These changes are common in people with and without back pain. They can sometimes contribute to stiffness and aching, but they do not doom you to a life of pain. Strength, mobility, and fitness still make a huge difference at any age.

Warning Signs: When to See a Professional Quickly

Most lower back pain is not an emergency. However, there are some red flags that mean you should see a doctor or physiotherapist promptly, or seek urgent care if they appear suddenly.

• Back pain after a significant fall, accident, or direct blow
• Constant pain that does not ease when you rest or lie down
• Strong pain at night that wakes you and does not change with position
• New weakness, heavy feeling, or giving way in one or both legs
• Numbness or tingling around the groin or inner thighs (saddle area)
• Sudden changes in bladder or bowel control (struggling to go or leaking when you normally wouldn’t)
• Unexplained weight loss, fever, or feeling very unwell alongside back pain
• Back pain in someone with a history of cancer, osteoporosis, or long-term steroid use

If you’re unsure, reach out to a health professional. It’s always okay to ask, “Is this something I should be worried about?”

Solutions and Relief: What Actually Helps?

Movement Is Medicine

It can feel natural to rest completely when your back hurts, but staying still for too long often makes things worse. Joints stiffen, muscles weaken, and your confidence in moving drops.

Instead, aim for gentle, regular movement:

• Short walks (even around the house at first)
• Changing position every 30–45 minutes
• Easy, pain-tolerable movements of your spine (bending, straightening, gentle twisting)

Think “keep it moving”, not “freeze and protect”.

Simple Exercises and Stretches

These are general exercises many people with lower back pain find helpful. They should be comfortable or only mildly uncomfortable, and your pain should not spike or stay worse afterwards. If you’re unsure, check with a physio before starting.

1. Knee-to-Chest

• Lie on your back with your knees bent and feet flat.
• Gently bring one knee towards your chest, holding behind the thigh or on top of the shin.
• Hold for 10–20 seconds, then switch legs.
• Repeat 5 times each side.

2. Cat-Cow

• Start on hands and knees with your hands under shoulders and knees under hips.
• Slowly arch your back up towards the ceiling, gently tucking your chin (cat).
• Then slowly let your back sink down, lifting your chest and looking slightly forward (cow).
• Move smoothly between these positions for 10–15 repetitions.

3. Bird-Dog

• On hands and knees, tighten your lower tummy muscles slightly.
• Reach one arm forward and the opposite leg back, keeping your hips level.
• Hold for 3–5 seconds, then lower and switch sides.
• Start with 6–8 repetitions per side.

4. Pelvic Tilts

• Lie on your back with knees bent and feet flat.
• Gently flatten your lower back towards the floor by tightening your lower tummy and tilting your pelvis slightly.
• Hold for 5 seconds, then relax.
• Repeat 10–15 times.

Build up gradually. A little, often is better than a long, intense session once a week.

Posture and Ergonomics Tips

You do not need to sit “perfectly” all day, but small tweaks can reduce strain:

• At your desk: Feet flat on the floor, hips and knees roughly at 90 degrees, screen at eye level, and your lower back supported by the chair or a small cushion.
• With laptops: Use a stand or stack of books to raise the screen, and use an external keyboard and mouse if possible.
• On the sofa: Sit a little more upright with a cushion behind your lower back and your feet supported, rather than slumped with your feet tucked under you for hours.
• On your phone: Bring the screen up towards your face instead of bending your neck down for long periods.

Most importantly: change position regularly. A “pretty good” posture that you move out of often beats a “perfect” posture you hold all day.

Heat vs. Ice

Both can help, and neither is magic. Use what feels best to you, with a few simple guidelines:

• Ice can be useful in the first 24–48 hours after a new flare-up, especially if there is a sense of heat or swelling. Wrap an ice pack in a cloth and apply for up to 10–15 minutes at a time.
• Heat (hot pack, warm shower, hot water bottle wrapped in a towel) often helps muscles relax and can ease stiffness. Again, 10–15 minutes is usually enough.

Always protect your skin and check for any reduced sensation before using heat or ice.

The Role of Physiotherapy

A physiotherapist is trained to assess how your spine, muscles, and nervous system are working together. In a typical session, you can expect:

• A clear conversation about your pain story, goals, and any concerns
• A movement and strength assessment to find what makes your pain better or worse
• Hands-on techniques if needed (such as mobilisation or soft tissue release) to help calm things down
• A tailored exercise plan to build strength, flexibility, and confidence
• Education about what is happening and how to manage flare-ups

The aim is not just to “fix” this episode, but to help you understand your back and feel in control for the long term.

Lifestyle Tweaks That Support Your Back

Your back is part of your whole body, not a separate machine. These changes can make a real difference over time:

• Sleep: Aim for roughly 7–9 hours. A medium-firm mattress suits many people, but comfort is key. Side sleepers often like a pillow between their knees.
• Stress: Try simple tools like walking, breathing exercises, or time outdoors to lower your stress level. This can dial down your pain sensitivity.
• Activity: Find movement you enjoy: walking, swimming, cycling, yoga, Pilates, or strength training. Consistency matters more than the “perfect” choice.
• Hydration and nutrition: Staying hydrated and eating a varied, balanced diet supports tissue health and recovery.

Key Takeaway: You Are Not Stuck With This Forever

Lower back pain can be frustrating, worrying, and exhausting. But in most cases, it is changeable. Your spine is strong. It responds well to the right mix of movement, strength, pacing, and support.

If you take one thing from this post, let it be this: you do not need to wait for your back to magically “fix itself” while you rest on the sofa. Gentle movement, simple exercises, and small lifestyle tweaks are powerful tools you can start using today.

And if you feel stuck, scared, or unsure where to begin, reach out to a physiotherapist. With the right guidance, most people can get back to the things that matter to them – not by avoiding movement, but by rebuilding confidence in how they move.
