To understand what a herniated disc is, it helps to first understand the role of the spinal discs.

Your spine is made up of a series of bones called vertebrae. Between each vertebra sits an intervertebral disc, a strong yet flexible structure that acts as a natural shock absorber. These discs allow the spine to move smoothly while helping distribute the forces generated during everyday activities such as walking, bending, lifting and twisting.

Each disc has two main components. The outer layer, known as the annulus fibrosus, is made of tough fibrous tissue that provides strength and stability. At its centre is a softer, gel-like core called the nucleus pulposus, which helps absorb pressure and maintain flexibility.

A herniated disc occurs when part of the inner material pushes through a weakened or damaged area of the outer layer. In some cases, this displaced material may come into contact with a nearby spinal nerve, potentially causing pain, numbness, tingling or weakness. In many other cases, however, a herniated disc causes no symptoms at all and is discovered only during imaging performed for another reason.

Disc changes often develop gradually as part of the natural ageing process. Over time, discs lose some of their water content and become less flexible, making them more susceptible to small tears or bulges. A sudden movement, heavy lifting or twisting motion may sometimes trigger symptoms, but in most cases a herniated disc is the result of changes that have developed over months or years rather than a single isolated event.

It is also important to understand that not all disc changes are the same. Healthcare professionals may describe findings such as a disc bulge, disc protrusion, disc extrusion or disc sequestration. These terms describe different appearances on imaging, but they do not necessarily predict how much pain a person will experience. Some people with a large disc herniation have very few symptoms, while others with relatively small changes may experience significant discomfort.

For this reason, imaging findings should always be interpreted alongside a thorough clinical examination rather than considered in isolation.

One of the most common misconceptions is that every herniated disc causes pain. In reality, this is not the case.

Modern imaging techniques, such as MRI, have shown that many people have disc bulges or herniated discs without experiencing any pain or other symptoms. In fact, age-related changes in the spine are extremely common and are often considered part of the normal ageing process. Many individuals discover they have a herniated disc only because they underwent imaging for an unrelated reason.

Pain usually occurs when a herniated disc irritates or compresses a nearby nerve root, or when inflammation develops around the affected tissues. Even then, the relationship between imaging findings and symptoms is not always straightforward. Two people with similar MRI results may have completely different experiences—one may have significant pain, while the other remains symptom-free.

The size of a herniated disc does not always determine how severe the symptoms will be. A relatively small herniation can sometimes cause considerable discomfort if it affects a sensitive nerve, whereas a larger herniation may produce very few symptoms if it does not interfere with surrounding structures.

For this reason, healthcare professionals do not base treatment decisions on MRI findings alone. Your symptoms, medical history and clinical examination are just as important as any imaging results. Understanding how your body functions in everyday life provides valuable information that cannot be seen on a scan.

What Are the Symptoms of a Herniated Disc?

The symptoms of a herniated disc vary depending on its location and whether nearby nerves are affected. Some people experience only local back or neck pain, while others develop symptoms that radiate into an arm or a leg.

A lumbar herniated disc, which affects the lower back, may irritate one of the nerve roots that form the sciatic nerve. This can lead to pain travelling through the buttock, thigh, calf or foot, commonly known as sciatica.

A cervical herniated disc, located in the neck, may cause pain that radiates into the shoulder, arm or hand. Some people also notice numbness, tingling or weakness in specific areas depending on the nerve involved.

Common symptoms may include:

• Pain in the lower back or neck.
• Pain radiating into the arm or leg.
• Numbness or reduced sensation.
• Tingling or pins-and-needles.
• Muscle weakness.
• Reduced mobility.
• Increased pain during certain movements or prolonged positions.

Symptoms may develop suddenly or appear gradually over time. They can also fluctuate, with periods of improvement followed by temporary flare-ups.

It is important to remember that leg pain is not always caused by a herniated disc, and not every episode of back pain indicates a disc injury. Several muscles, joints, ligaments and nerves can produce similar symptoms, which is why a comprehensive clinical assessment is essential before establishing the most appropriate management plan.

What Causes a Herniated Disc?

Many people believe that a herniated disc is caused by a single event, such as lifting a heavy box or bending awkwardly. While these activities may trigger the onset of symptoms, the changes within the disc often develop gradually over time.

Intervertebral discs naturally change as we age. They slowly lose water content and become less flexible, making them more susceptible to small tears within the outer fibres. These changes are a normal part of ageing and do not necessarily cause pain.

Several factors may increase the likelihood of developing a symptomatic herniated disc. Repetitive lifting, physically demanding work, prolonged sitting, smoking, reduced physical conditioning and certain genetic factors have all been associated with disc degeneration. However, no single factor fully explains why one person develops symptoms while another does not.

Regular physical activity is often beneficial for overall spinal health. Contrary to popular belief, movement itself is not harmful to the discs. In fact, gradually exposing the spine to appropriate levels of physical activity helps maintain strength, mobility and resilience over time.

For most people, a herniated disc is the result of multiple interacting factors rather than one isolated incident. Understanding these factors allows treatment to focus not only on relieving current symptoms but also on supporting long-term spinal health and reducing the risk of future episodes.

How Is a Herniated Disc Diagnosed?

Diagnosing a herniated disc involves much more than looking at an MRI scan. While imaging can provide valuable information in certain situations, the diagnosis begins with a thorough clinical assessment.

During your first consultation, your chiropractor will take the time to understand your symptoms, your medical history and how your condition affects your daily life. You will be asked when the pain started, whether it appeared suddenly or gradually, what movements aggravate or relieve your symptoms, and whether you experience numbness, tingling or muscle weakness.

This detailed discussion is followed by a comprehensive physical examination designed to identify the structures that may be contributing to your symptoms.

The examination may include an assessment of:

• Spinal mobility.
• Joint function.
• Muscle strength.
• Reflexes.
• Sensation.
• Coordination.
• Orthopaedic and neurological tests when clinically appropriate.

These findings help determine whether your symptoms are consistent with a herniated disc or whether another musculoskeletal condition may be responsible.

A thorough assessment also allows your chiropractor to identify red flags—signs or symptoms that may require further medical investigation or referral to another healthcare professional.

Every treatment plan begins with understanding you, not simply your imaging results.

Do I Need an MRI?

Many people believe that an MRI is necessary whenever back pain or sciatica develops. In reality, this is not always the case.

Current clinical guidelines recommend that imaging should be used selectively rather than routinely. Most episodes of back pain and many cases of suspected disc herniation can be assessed safely through a detailed history and physical examination.

An MRI may be recommended if your symptoms suggest significant nerve involvement, if serious underlying conditions need to be ruled out, or if symptoms fail to improve despite appropriate conservative management.

Imaging is also important when surgery or other specialist interventions are being considered.

One of the reasons MRI is not routinely performed is that spinal changes are extremely common, even in people who have no pain. Studies have shown that many healthy adults have disc bulges, disc degeneration or even herniated discs without experiencing any symptoms. For this reason, MRI findings should always be interpreted alongside your clinical presentation.

Treating an MRI rather than the person can sometimes lead to unnecessary concern or interventions. A comprehensive clinical assessment provides a much clearer understanding of what may be contributing to your symptoms and whether imaging is actually required.

How Chiropractic Care May Help

Not every herniated disc requires the same approach. The most appropriate management depends on your symptoms, the findings of your clinical examination and your overall health.

When chiropractic care is appropriate, the aim is not to "push the disc back into place" or "realign the spine." Instead, treatment focuses on improving the way your spine and surrounding tissues function, reducing mechanical stress where possible, supporting recovery and helping you return to your normal activities with confidence.

Your care plan is always individualised and may evolve as your symptoms improve.

Improving Spinal Mobility

Pain often changes the way we move. During an episode of disc-related pain, some areas of the spine may become stiff while others compensate by moving more than usual. These altered movement patterns can contribute to ongoing discomfort and reduced function.

When clinically indicated, chiropractic adjustments and other manual therapy techniques may help improve joint mobility and restore more balanced movement throughout the spine. These techniques are always adapted to your symptoms, age and overall health.

The goal is to improve function rather than simply treat a painful area.

Reducing Muscle Tension

People with a herniated disc frequently develop increased muscle tension around the affected region. This protective response is completely normal, but when it persists it may contribute to stiffness, fatigue and discomfort.

Depending on your examination findings, your chiropractor may use a combination of soft tissue techniques to help reduce excessive muscle tension and improve comfort.

When appropriate, additional approaches such as Dry Needling or therapeutic cupping may also be incorporated into your personalised treatment plan.

These techniques are selected according to your individual presentation and are always used as part of a broader rehabilitation strategy rather than as standalone treatments.

Recovery and rehabilitation 

Recovering from a herniated disc is rarely about complete rest. While it may be tempting to avoid movement because of pain, prolonged inactivity can sometimes delay recovery by contributing to stiffness, muscle weakness and reduced confidence in movement.

For most people, remaining as active as symptoms allow is encouraged. Gentle, progressive movement helps maintain joint mobility, supports circulation and promotes the normal function of muscles and nerves. The key is to find the right balance between protecting the irritated tissues and avoiding unnecessary inactivity.

Recovery is different for everyone. Some people improve within a few weeks, while others require several months to regain full function. The severity of symptoms, the presence of nerve irritation, general health and activity levels can all influence the recovery process.

Rather than focusing solely on pain relief, rehabilitation aims to restore normal movement, improve strength and help you return to your everyday activities with greater confidence.

Returning to Movement Safely

One of the biggest challenges after a herniated disc is overcoming the fear of movement.

Many people worry that bending, lifting or twisting will make the disc worse. While some movements may temporarily increase symptoms during the early stages, avoiding movement altogether is rarely beneficial.

As pain settles, gradually reintroducing normal daily activities helps the spine adapt and regain its natural capacity to tolerate load. Your chiropractor can help you understand which movements are appropriate at each stage of recovery and suggest practical modifications when needed.

The goal is not to avoid movement but to build confidence and restore normal function safely and progressively.

Personalised Exercise Programmes

Exercise plays an important role in the conservative management of many herniated discs.

Following your assessment, your chiropractor may recommend a personalised rehabilitation programme based on your symptoms, physical examination and individual goals.

Depending on your needs, your programme may focus on improving spinal mobility, restoring flexibility, strengthening the muscles that support the spine and pelvis, enhancing balance and coordination, and gradually increasing your tolerance to everyday activities.

As your recovery progresses, your exercises will be adjusted to match your improving function, allowing you to return safely to work, sport and other activities you enjoy.

Rather than following a generic routine, rehabilitation is tailored to your individual presentation and evolves as your condition changes.

Can a Herniated Disc Heal Naturally?

One of the questions patients ask most often is whether a herniated disc can heal on its own.

The encouraging answer is that many herniated discs improve over time without surgery.

The human body has remarkable healing mechanisms. In many cases, the inflammation surrounding the affected nerve gradually settles, symptoms become less intense and the body may even reabsorb part of the herniated disc material through natural biological processes.

This does not necessarily mean that the disc returns completely to its original appearance on imaging. More importantly, many people experience significant improvements in pain and function regardless of what a follow-up MRI might show.

Recovery depends on several factors, including the type of disc herniation, the degree of nerve irritation, your overall health and how your body responds to treatment. While no healthcare professional can predict exactly how quickly an individual will recover, most people improve with an appropriate conservative management plan.

The aim of chiropractic care is to support this natural recovery process by improving spinal function, encouraging safe movement, reducing mechanical stress where appropriate and helping you regain confidence in your body.

When Is Surgery Necessary?

Learning that you have a herniated disc does not automatically mean that surgery will be required.

In fact, most people recover successfully with conservative care, which may include education, activity modification, exercise and, when appropriate, chiropractic treatment.

Surgery is generally considered only when specific medical indications are present. These may include progressive muscle weakness, severe neurological deficits, symptoms of cauda equina syndrome or persistent pain that has not responded to an appropriate course of conservative treatment.

If your symptoms or examination findings suggest that further medical investigation is necessary, your chiropractor will ensure that you are referred to the appropriate healthcare professional without delay.

Your safety always comes first, and recognising when chiropractic care is appropriate—and when another form of medical management is needed—is an essential part of evidence-informed practice.

Preventing Future Episodes

Although it is not always possible to prevent a herniated disc, adopting healthy habits can help reduce stress on your spine and lower the risk of future episodes of back pain.

One of the most important things you can do is stay physically active. Regular movement helps maintain the strength, flexibility and endurance of the muscles that support your spine. Walking, swimming, cycling and strength training are all excellent ways to promote long-term spinal health.

Good lifting technique also plays an important role. Rather than avoiding lifting altogether, learning how to lift efficiently and progressively build your body's capacity to tolerate everyday loads can help reduce unnecessary strain on the lower back.

Prolonged sitting is another common contributor to back discomfort. If your work involves spending long hours at a desk, taking short movement breaks every 30 to 60 minutes can help reduce stiffness and improve circulation. Small changes to your workstation, chair height and screen position may also improve comfort throughout the day.

Maintaining strong core, hip and lower limb muscles provides additional support for the spine during everyday activities. A well-designed exercise programme can improve movement control, balance and overall physical resilience while reducing the likelihood of recurrent episodes.

Sleep, stress management and general health also influence recovery. Poor sleep quality, persistent stress and smoking have all been associated with an increased risk of persistent back pain. Looking after your overall health is therefore an important part of caring for your spine.

At the Cabinet de Chiropraxie Marie Moyen, we believe that education is an essential part of treatment. Understanding your condition and learning how to move with confidence can help you become an active participant in your recovery rather than relying solely on passive treatments.

When Should You Seek Immediate Medical Attention?

Although most herniated discs improve with conservative management, certain symptoms require urgent medical assessment.

Seek immediate medical attention if you experience a sudden loss of bladder or bowel control, numbness around the inner thighs or saddle area, or rapidly worsening weakness in one or both legs. These symptoms may indicate cauda equina syndrome, a rare but serious medical emergency that requires prompt treatment.

You should also seek urgent medical advice if severe back pain develops after a significant fall or accident, if it is accompanied by fever, unexplained weight loss or persistent night pain, or if your symptoms continue to worsen despite appropriate care.

Your chiropractor is trained to recognise these warning signs during the clinical examination. If your symptoms suggest that further medical investigation or specialist care is required, you will be referred promptly to the most appropriate healthcare professional.

Your safety is always our highest priority.

Living Well with a Herniated Disc

A diagnosis of a herniated disc can feel overwhelming, but it does not define your future. Many people return to work, sport and the activities they enjoy through appropriate conservative care, gradual rehabilitation and an active approach to recovery.

Understanding your condition is often the first step towards feeling more confident. Pain does not always reflect the extent of tissue damage, and many people improve significantly over time even when MRI findings remain unchanged.

Rather than focusing solely on the image of a disc, effective management aims to improve how your spine functions as a whole. Restoring movement, improving strength, reducing unnecessary fear of activity and building long-term resilience are all key components of recovery.

Every person is different, which is why treatment should always be tailored to your individual symptoms, examination findings and personal goals. A personalised approach allows care to evolve as your condition improves and helps support a safe return to the activities that matter most to you.

Whether your symptoms began recently or have been present for several months, a comprehensive assessment can help identify the factors contributing to your pain and guide the most appropriate management strategy.
