Understanding Lower Back Pain and Its Connection to Sciatica
Lower back pain is one of the most common reasons people seek medical help. It affects people of all ages and lifestyles, from office workers and drivers to runners, golfers, gardeners and manual labourers. For some, it is a mild inconvenience that settles within a few days. For others, it becomes persistent, limiting work, sleep, hobbies and quality of life.
At Buxton & Bakewell Osteopathy Clinic, we see patients from across Buxton, Bakewell, the Peak District and surrounding areas who have often tried painkillers, rest or even months of treatment elsewhere without finding lasting relief. One of the most important things we explain is that lower back pain is not a diagnosis—it is a symptom. Understanding why your back hurts is the key to choosing the right treatment.
Sometimes lower back pain remains localised to the spine. In other cases it travels into the buttock, thigh or leg, producing what is commonly known as sciatica. Knowing the difference between ordinary lower back pain and pain caused by nerve compression is essential because treatment approaches can differ considerably.
This guide explains the most common causes of lower back pain, how they relate to sciatica, what symptoms you should never ignore and the modern treatment options available.
What Is Lower Back Pain?
Lower back pain refers to pain arising from the lumbar spine—the lowest five vertebrae of the back (L1-L5)—or from the surrounding muscles, joints, ligaments, discs or nerves.
Although many people think of the spine as a single structure, it is actually made up of numerous tissues working together.
These include:
- Vertebrae
- Intervertebral discs
- Facet joints
- Ligaments
- Tendons
- Muscles
- Nerve roots
- Blood vessels
- Fascia
Pain can arise from any one of these structures or, quite commonly, from several at the same time.
This explains why two people with “lower back pain” may experience completely different symptoms.
Understanding Your Lumbar Spine
The lumbar spine is designed to provide both strength and flexibility.
It supports almost the entire weight of the upper body while allowing you to:
- Walk
- Bend
- Twist
- Lift
- Sit
- Stand
- Run
Every movement places forces through the discs and joints.
Over many years these tissues naturally age, but injury, repetitive strain, poor movement patterns or sudden trauma can accelerate this process.
The Vertebrae
The lumbar spine contains five large bones called vertebrae.
These provide:
- Stability
- Protection for the spinal cord
- Attachment points for muscles and ligaments
The vertebrae become progressively larger lower down the spine because they bear increasing body weight.
The Intervertebral Discs
Between each vertebra sits a shock absorber known as an intervertebral disc.
Each disc consists of:
Outer Annulus
A strong ring of collagen fibres that contains the disc.
Inner Nucleus
A softer gel-like centre designed to absorb compressive forces.
Healthy discs behave rather like hydraulic cushions.
Over time, however, they may:
- Lose water
- Develop small tears
- Bulge
- Herniate
- Degenerate
When this occurs they may irritate nearby nerves and produce sciatica.
Facet Joints
Each vertebra connects with the next via small joints called facet joints.
These guide movement and provide stability.
Like any other joint, they can become:
- Arthritic
- Inflamed
- Stiff
- Painful
Facet joint pain often produces aching lower back pain without symptoms travelling far down the leg.
Muscles
Numerous muscles support the spine.
These include:
- Multifidus
- Erector spinae
- Quadratus lumborum
- Gluteal muscles
- Deep abdominal muscles
Muscles may become strained through:
- Heavy lifting
- Sport
- Gardening
- Poor posture
- Prolonged sitting
Fortunately muscular injuries usually recover more quickly than disc injuries.
Ligaments
Strong ligaments connect each vertebra.
These prevent excessive movement while allowing normal flexibility.
Sudden twisting injuries or falls can overstretch these structures causing localised pain and stiffness.
Nerves
The spinal cord finishes around the level of the first lumbar vertebra.
Below this point numerous nerve roots continue down through the spinal canal before exiting between the vertebrae.
These nerve roots eventually form the sciatic nerve, the largest nerve in the body.
If one of these nerve roots becomes compressed or inflamed, pain may radiate into the leg.
This is known as sciatica.
Is Lower Back Pain the Same as Sciatica?
No.
This is probably the biggest misconception we encounter.
Many patients believe that all lower back pain is sciatica.
In reality:
Most lower back pain is not sciatica.
Sciatica is a specific condition involving irritation or compression of one or more lumbar nerve roots.
Typical features include:
- Pain travelling below the buttock
- Pain down the thigh
- Pain into the calf
- Pain into the foot
- Pins and needles
- Numbness
- Burning pain
- Electric shock sensations
- Weakness
Someone with muscular lower back pain may have severe back pain but absolutely no leg symptoms.
Conversely, someone with a disc prolapse may have surprisingly little back pain but severe leg pain.
Understanding this distinction is crucial when deciding the most appropriate treatment.
Why Does Lower Back Pain Sometimes Become Sciatica?
Sciatica develops when one of the nerve roots leaving the lower spine becomes irritated.
This irritation may occur because of:
- Mechanical compression
- Chemical inflammation
- Swelling
- Reduced space around the nerve
The nerve then sends pain signals along its entire length.
This explains why a problem in your lower back can produce symptoms in your:
- Buttock
- Hip
- Thigh
- Calf
- Ankle
- Foot
- Toes
Common Causes of Lower Back Pain
There are many possible causes.
Some are relatively simple.
Others require more specialist assessment.
1. Muscle Strain
The most common cause.
Often develops after:
- Lifting
- Twisting
- Sport
- DIY
- Gardening
- Sudden awkward movement
Pain is usually localised.
Movement is painful but neurological symptoms are absent.
Recovery typically occurs within a few weeks.
2. Disc Bulge
Discs gradually lose water with age.
Sometimes the outer wall weakens allowing the disc to bulge.
Small bulges are common and often painless.
Larger bulges may narrow the space available for nerves.
3. Herniated Disc
Sometimes called:
- Slipped disc
- Prolapsed disc
- Ruptured disc
Although “slipped disc” is widely used, discs do not actually slip.
Instead, part of the soft centre pushes through a tear in the outer wall.
If this material presses on a nerve root, sciatica may develop.
Symptoms often include:
- Sharp leg pain
- Tingling
- Numbness
- Muscle weakness
4. Degenerative Disc Disease
As discs age they lose height and flexibility.
This natural ageing process may become painful if excessive.
Symptoms often include:
- Morning stiffness
- Aching back
- Difficulty sitting
- Pain after lifting
- Recurrent episodes
5. Facet Joint Syndrome
Small arthritic joints become inflamed.
Pain usually remains in:
- Lower back
- Buttock
It rarely travels below the knee.
Extension (leaning backwards) often aggravates symptoms.
6. Spinal Stenosis
The spinal canal gradually narrows.
This reduces the available space for nerves.
Typical symptoms include:
- Walking intolerance
- Leg pain
- Tingling
- Heaviness
- Symptoms eased by sitting or bending forwards
Spinal stenosis is particularly common in people over 60.
7. Spondylolisthesis
One vertebra slips forwards relative to another.
This may:
- Narrow nerve exits
- Irritate nerve roots
- Produce instability
- Cause sciatica
8. Sacroiliac Joint Dysfunction
The sacroiliac joints connect the spine to the pelvis.
Pain is commonly felt:
- One side of the lower back
- Buttock
- Groin
It can sometimes mimic sciatica.
9. Osteoarthritis
Arthritic changes affecting the spine may contribute to stiffness, pain and reduced movement.
These changes often coexist with disc degeneration.
10. Trauma
Falls…
Road traffic accidents…
Sports injuries…
Heavy lifting accidents…
These may damage:
- Muscles
- Ligaments
- Discs
- Facet joints
- Vertebrae
Common Symptoms of Lower Back Pain
Lower back pain presents differently from person to person.
Common symptoms include:
| Symptom | Possible Cause |
|---|---|
| Localised lower back pain | Muscle strain, facet joints |
| Pain after lifting | Disc injury, muscle strain |
| Morning stiffness | Arthritis, disc degeneration |
| Pain sitting | Disc injury |
| Pain standing | Facet joints, stenosis |
| Pain bending | Disc injury |
| Buttock pain | SI joint, disc, muscles |
| Pain below the knee | Sciatica |
| Pins and needles | Nerve irritation |
| Numbness | Nerve compression |
| Weakness | Nerve compression |
| Foot drop | Significant nerve compression (urgent assessment needed) |
How Does Lower Back Pain Affect Everyday Life?
Persistent lower back pain can have a profound impact on daily activities. Simple tasks such as putting on socks, lifting shopping bags, getting out of the car or sitting through a meeting may become difficult. Many people also find that disturbed sleep, reduced physical activity and the frustration of ongoing pain begin to affect their mood and confidence.
Over time, fear of movement can develop. People may avoid exercise or activities they once enjoyed because they worry about making the pain worse. Unfortunately, this can lead to muscle weakness, reduced fitness and greater stiffness, creating a cycle that becomes increasingly difficult to break.
Diagnosis, MRI Scans and Modern Treatment Options
If your lower back pain has persisted for more than a few weeks, keeps returning, or is accompanied by leg pain, numbness or weakness, it is important to determine the underlying cause rather than simply treating the symptoms.
Many patients who visit Buxton & Bakewell Osteopathy Clinic have already tried painkillers, massage, exercises or even several courses of physiotherapy without lasting improvement. Often, this is because treatment has focused on relieving pain rather than identifying the structure responsible for it.
A thorough assessment is the foundation of successful treatment.
Why Getting the Correct Diagnosis Matters
Not all lower back pain is the same.
Two patients may both complain of severe pain, yet one may have a simple muscular strain while the other has a prolapsed disc compressing the sciatic nerve.
Likewise, someone with severe MRI findings may have very little pain, while another patient with only minor changes may experience debilitating symptoms.
Treating the correct diagnosis—not simply the scan—is one of the most important principles of modern spinal care.
Your Initial Assessment
At Buxton & Bakewell Osteopathy Clinic, every assessment begins with a detailed consultation.
Understanding exactly how your symptoms started often provides valuable clues.
Your clinician will ask questions such as:
- When did your pain begin?
- Was there a specific injury?
- Does the pain stay in your back or travel into your leg?
- Which activities make it worse?
- What makes it feel better?
- Is the pain constant or intermittent?
- Do you experience pins and needles or numbness?
- Have you noticed any weakness?
- Have you had previous episodes?
- Have previous treatments helped?
This information helps narrow down the likely cause before the physical examination even begins.
Physical Examination
Your osteopath will then perform a comprehensive examination.
This may include:
Posture Assessment
Poor posture rarely causes lower back pain on its own but can contribute to excessive strain over time.
We assess:
- Standing posture
- Sitting posture
- Pelvic alignment
- Lumbar curve
- Weight distribution
Movement Assessment
We assess how your spine moves.
Typical movements include:
- Forward bending
- Backward bending
- Side bending
- Rotation
The pattern of pain often provides valuable diagnostic information.
For example:
Pain bending forwards often suggests disc involvement.
Pain leaning backwards may indicate facet joint irritation or spinal stenosis.
Neurological Examination
If sciatica is suspected, a neurological examination is essential.
This includes assessment of:
- Muscle strength
- Reflexes
- Skin sensation
- Walking pattern
- Balance
- Coordination
Specific muscles supplied by different nerve roots are tested.
This helps determine exactly which spinal nerve may be affected.
Nerve Tension Tests
Special clinical tests help determine whether the sciatic nerve is irritated.
Common examples include:
Straight Leg Raise
One of the most widely used tests for lumbar disc injuries.
Pain travelling below the knee during this test may indicate nerve root irritation.
Slump Test
A sensitive assessment for nerve mobility.
This test places gentle tension through the nervous system to identify nerve irritation.
Femoral Nerve Stretch Test
Used when symptoms suggest compression of the upper lumbar nerves rather than the sciatic nerve.
Orthopaedic Tests
Additional clinical tests help identify problems involving:
- Facet joints
- Sacroiliac joints
- Hip joints
- Muscles
- Ligaments
Because several structures can produce similar symptoms, combining multiple examination findings improves diagnostic accuracy.
When Is an MRI Scan Helpful?
Many people believe everyone with back pain should have an MRI. We do provide fast and affordable private MRI Scans
In reality, this is rarely necessary.
Most uncomplicated episodes improve without imaging.
However, MRI can be extremely valuable when:
- Symptoms persist despite treatment
- Sciatica is severe
- Weakness develops
- Surgery is being considered
- IDD Therapy is being planned
- Serious pathology needs excluding
MRI provides detailed images of:
- Intervertebral discs
- Nerve roots
- Ligaments
- Facet joints
- Spinal canal
- Bone marrow
Unlike X-rays, MRI does not use radiation.
What Can an MRI Show?
MRI may identify:
The most common cause of sciatica in younger adults.
Disc Bulge
Common with ageing.
May or may not produce symptoms.
Shows reduced disc height and dehydration.
Narrowing around the nerves.
Often seen in older adults.
Forward movement of one vertebra.
Nerve Compression
Perhaps the most important finding when investigating sciatica.
Arthritis
Facet joint degeneration.
MRI Findings Must Be Interpreted Carefully
One of the biggest misconceptions is that every MRI abnormality explains pain.
Research has shown that many people with no symptoms have:
- Disc bulges
- Disc degeneration
- Arthritis
For this reason, MRI findings should always be interpreted alongside:
- Symptoms
- Examination findings
- Medical history
Treating MRI pictures instead of patients often leads to poor outcomes.
Conservative Treatment
Fortunately, most lower back pain improves without surgery.
The goal is to reduce pain while restoring normal movement, strength and confidence.
Osteopathy
Osteopathy focuses on improving movement throughout the spine and surrounding tissues.
Treatment may include:
- Gentle spinal mobilisation
- Soft tissue techniques
- Joint articulation
- Stretching
- Muscle energy techniques
- Exercise prescription
Treatment is always tailored to the individual’s diagnosis.
Exercise Rehabilitation
Movement is one of the most important components of recovery.
Appropriate exercises help:
- Improve flexibility
- Restore spinal movement
- Strengthen supporting muscles
- Reduce recurrence
- Improve confidence
Modern rehabilitation is based on gradual progression rather than prolonged rest.
Why Rest Alone Is Rarely the Answer
Years ago, patients were advised to stay in bed.
Current evidence suggests prolonged rest may actually delay recovery.
Remaining as active as symptoms allow generally produces better outcomes.
IDD Therapy
For patients with persistent disc-related lower back pain or sciatica, IDD Therapy® may offer an effective non-surgical treatment option.
IDD Therapy uses a computer-controlled spinal decompression system to gently distract the affected spinal segment.
Unlike ordinary traction, treatment is carefully targeted to the specific level of injury.
This may help:
- Reduce pressure within damaged discs
- Decrease nerve irritation
- Improve spinal mobility
- Reduce muscle spasm
- Encourage improved nutrient exchange within the disc
IDD Therapy is commonly considered for patients with:
- Herniated discs
- Bulging discs
- Degenerative disc disease
- Chronic sciatica
- Spinal stenosis
- Persistent nerve compression and trapped nerves
Many patients choose IDD Therapy when they wish to explore non-surgical options before considering injections or surgery.
Focused Shockwave Therapy
Although shockwave therapy is best known for treating tendon injuries, it can also play a role in selected cases of lower back pain.
It may help:
- Chronic muscular pain
- Trigger points
- Tendon attachments
- Persistent soft tissue dysfunction
Focused Shockwave Therapy stimulates healing while reducing pain sensitivity.
Radial Shockwave Therapy
Radial Shockwave Therapy is particularly useful for:
- Muscle tightness
- Fascial restrictions
- Chronic soft tissue pain
It is often combined with rehabilitation exercises to improve long-term outcomes.
Low Level Laser Therapy
Low Level Laser Therapy delivers light energy to damaged tissues.
Potential benefits include:
- Reduced inflammation
- Improved cellular repair
- Pain reduction
- Enhanced healing
Laser therapy is frequently used alongside manual treatment and exercise rather than as a stand-alone treatment.
Lifestyle Advice
Recovery often depends on small changes made every day.
Patients may benefit from advice regarding:
- Sitting posture
- Home working
- Lifting technique
- Sleep position
- Walking
- Exercise progression
- Weight management
These simple measures can reduce strain on the spine and help prevent recurrence.
When Is Surgery Needed?
Fortunately, only a small percentage of people with lower back pain require surgery.
Surgery may be considered when:
- Progressive weakness develops
- Significant nerve compression is present
- Severe pain persists despite appropriate treatment
- Cauda equina syndrome occurs
- Loss of bowel or bladder control develops
Even in these situations, the decision should be made after careful assessment by a spinal specialist.
When Should You Seek Urgent Medical Attention?
Most episodes of lower back pain are not medical emergencies.
These symptoms require immediate medical assessment and should never be ignored.
Looking Ahead
Accurate diagnosis is the cornerstone of successful treatment. By combining a detailed history, clinical examination and imaging where appropriate, it is usually possible to identify the underlying cause of lower back pain and tailor treatment accordingly. Whether the problem arises from a muscle strain, a prolapsed disc or nerve compression causing sciatica, an evidence-informed plan offers the best chance of recovery.
Recovery, Prevention, When to Seek Urgent Help and Why Choose Buxton & Bakewell Osteopathy Clinic
Recovering from lower back pain is rarely about simply waiting for symptoms to disappear. Successful recovery involves understanding the cause of the problem, following an appropriate treatment plan and gradually restoring confidence in movement. Although many people improve within a few weeks, others experience recurring episodes because the underlying cause has never been properly addressed.
At Buxton & Bakewell Osteopathy Clinic, we believe recovery should focus on restoring function, improving resilience and helping patients return to the activities they enjoy, whether that is walking in the Peak District, gardening, playing golf or simply sitting comfortably at work.
Staying Active During Recovery
Years ago, prolonged bed rest was commonly recommended for lower back pain. Research now shows that, in most cases, remaining gently active leads to better outcomes.
This does not mean exercising through severe pain, but rather maintaining sensible movement wherever possible.
Activities that often help include:
- Gentle walking
- Light stretching
- Swimming
- Controlled mobility exercises
- Individual rehabilitation programmes
Movement improves circulation, reduces stiffness and helps maintain muscle strength, all of which contribute to recovery.
Returning to Work
Many patients worry that returning to work too soon will make their back worse. In reality, returning to normal activities in a controlled way is often beneficial.
Depending on your occupation, you may need temporary adjustments such as:
- More frequent breaks
- Altered lifting techniques
- A phased return
- Improved workstation ergonomics
- Reduced heavy manual tasks
The aim is to keep you active while protecting healing tissues.
Returning to Exercise and Sport
One of the most common questions we hear is, “When can I get back to the gym, running or golf?”
The answer depends on:
- Your diagnosis
- Pain levels
- Strength
- Movement quality
- Confidence
Returning too quickly may increase the risk of recurrence, while waiting too long can lead to deconditioning.
A gradual progression is usually safest.
Preventing Future Episodes
Lower back pain often returns because the original contributing factors remain unchanged.
Simple preventative measures include:
- Maintaining a healthy weight
- Keeping physically active
- Strengthening your core muscles
- Improving hip flexibility
- Avoiding prolonged sitting
- Using good lifting technique
- Taking regular movement breaks
- Managing stress
- Getting adequate sleep
Small lifestyle changes can significantly reduce the likelihood of future episodes.
Looking After Your Spine
Your spine is remarkably strong and designed for movement.
Many people become fearful after experiencing lower back pain and begin avoiding bending, lifting or exercise altogether.
In most cases, this is neither necessary nor helpful.
Instead, the goal should be to gradually rebuild confidence while improving strength and movement quality.
When Should You Seek Urgent Medical Attention?
Although most lower back pain is not serious, some symptoms require immediate medical assessment.
Seek urgent medical advice if you develop:
- Loss of bladder control
- Loss of bowel control
- Difficulty starting urination
- Numbness around the buttocks or genitals (saddle numbness)
- Progressive leg weakness
- Foot drop
- Severe weakness affecting walking
- Pain following significant trauma
- Fever associated with severe back pain
- Unexplained weight loss with persistent pain
- History of cancer with new back pain
These symptoms may indicate a serious condition requiring urgent investigation.
Cauda Equina Syndrome
One of the most important spinal emergencies is Cauda Equina Syndrome
If these symptoms develop, you should seek immediate emergency medical attention. Early diagnosis and treatment are essential.
Why Early Assessment Matters
Many patients hope that persistent lower back pain will simply settle with time. While this is true for some, delaying assessment can sometimes allow symptoms to worsen, particularly if a nerve is becoming increasingly irritated.
Early assessment provides:
- A clear diagnosis
- Appropriate advice
- Timely treatment
- Faster recovery
- Reduced risk of persistent pain

Frequently Asked Questions
Can lower back pain cause sciatica?
Yes. If a lumbar nerve root becomes compressed or irritated, pain may travel from the lower back into the buttock, leg and foot.
Do all disc bulges cause pain?
No. Many people have disc bulges without symptoms. Treatment is based on your symptoms and examination rather than MRI findings alone.
Is walking good for lower back pain?
For most people, gentle walking is beneficial as it encourages movement, improves circulation and helps reduce stiffness.
Should I stay in bed?
Extended bed rest is rarely recommended. Remaining gently active usually leads to a quicker recovery.
When do I need an MRI scan?
MRI is generally recommended when symptoms persist, neurological signs develop or further investigation is needed.
Can osteopathy help lower back pain?
Many patients benefit from osteopathic treatment as part of a comprehensive rehabilitation programme.
What is IDD Therapy®?
IDD Therapy® is a computer-controlled spinal decompression treatment used for selected patients with disc-related lower back pain and sciatica.
Can sciatica improve without surgery?
Yes. Most cases improve with appropriate conservative management.
How can I reduce the risk of lower back pain returning?
Regular exercise, good posture, maintaining strength and addressing the underlying cause all reduce recurrence.
When should I seek urgent help?
Immediately if you develop bladder or bowel problems, saddle numbness or rapidly worsening leg weakness.
