Bulging Discs: The Common Causes
A herniated disc is one of the most common causes of back pain for Australians, and, let’s face it, with the way our way of life is rapidly changing to a more sedentary lifestyle, we can expect that more and more people will be affected. That is, if we do nothing about it. So let’s not be passive but find solutions, starting by understanding what causes a herniated disc, how it manifests, and ultimately what the treatments are.
What Causes a Herniated Disc?
According to the National Health Survey conducted by the Australian Bureau of Statistics, about 4 million people in Australia live with back problems, and out of those 4 million, approximately 43% suffer from vertebrae and disc disorders. Thus, a bulging disc is a rather common malady in today’s day and age. So what causes a herniated disc?
A herniated/bulging/slipped disc happens when one of the soft, gel-like cushions (discs) between the bones in your spine (vertebrae) is damaged. These discs act as shock absorbers, helping your spine bend and move smoothly. Over time, or due to specific injuries, the tough outer layer of the disc can weaken or tear, allowing the softer inner material to push through. This puts pressure on nearby nerves, which can lead to pain and discomfort.
There are several common reasons why a disc might become herniated. Natural wear and tear is a major factor, especially as the discs in your spine lose flexibility and hydration with age. Repetitive movements, poor lifting techniques, and traumatic injuries such as a fall can also contribute to a disc bulging or rupturing.
In addition to these direct causes, certain factors can increase your risk of developing a herniated disc, including:
- Aging – As you get older, the protective outer layer of your discs weakens naturally;
- Genetics – Some people simply inherit a predisposition to spinal issues, making them more likely to experience disc problems.
- Sedentary lifestyle – Sitting for extended periods, especially with poor posture, places extra strain on your spine;
- Excess weight – Carrying extra weight, particularly around the midsection, puts additional pressure on your lower back;
- Smoking – Smoking can reduce blood flow to the spinal discs, making them more vulnerable to damage;
- Repetitive motions – Jobs or activities involving frequent bending, lifting, or twisting can increase the strain on your spine.
Symptoms of a Bulging Disc
A herniated disc can cause a variety of symptoms, depending on its location and whether it’s pressing on a nearby nerve. In many cases, you may not even realise you have a herniated disc, as some people experience little to no pain. However, when symptoms do appear, they can range from mild to severe and may interfere with your daily life.
The most common symptoms are:
- Pain – This is usually the first and most noticeable sign. If the herniated disc is in your lower back, the pain may radiate through your buttocks, thighs, and legs (commonly known as sciatica). If it’s in your neck, the pain may spread to your shoulders and arms.
- Numbness or tingling: Many people with a herniated disc describe feeling a pins and needles sensation in the affected area, which can extend to your limbs.
- Weakness: A herniated disc can impact the nerves that control your muscles, leading to muscle weakness in your arms or legs. You might notice difficulty lifting objects, walking, or gripping items.
Reduced range of motion: Stiffness and discomfort from the herniated disc can limit how much you’re able to move your back or neck.
It’s worth noting that symptoms often vary depending on the severity of the condition and which part of the spine is affected. For instance, a herniated disc in the lower back region may cause leg pain, while one in the neck area can lead to arm or shoulder discomfort.
However, if you’re experiencing severe pain, numbness, or even loss of bladder or bowel control, it’s crucial to seek medical attention immediately. These could be signs of a more serious condition than a bulging disc, such as cauda equina syndrome, which requires urgent treatment.
How Is a Bulging Disc Diagnosed?
Besides feeling these symptoms of a herniated disc, diagnosing the condition typically involves a combination of a physical exam and imaging tests. Your medical provider will start by discussing your symptoms and medical history, followed by a physical examination to check your range of motion, muscle strength, and reflexes. They may ask you to perform specific movements to identify which nerves might be affected.
If further confirmation is needed, imaging tests such as an MRI or CT scan are often used to get a detailed look at your spine and pinpoint the exact location of the herniated disc. In some cases, an X-ray might also be ordered to rule out other conditions, such as fractures or arthritis. These diagnostic tools help provide a clear picture of what’s happening in your spine, allowing the appropriate treatment to be planned.
Treatments for a Bulging Disc
The treatment for a bulging disc typically depends on the severity of your symptoms and how much they’re impacting your daily life. For many people, non-invasive treatments are enough to relieve pain and support the healing process. Common treatment options include:
- Rest and Activity Modification – Giving your spine a break and avoiding activities that worsen the pain can help reduce inflammation and promote recovery. However, prolonged bed rest is usually discouraged, as gentle movement is important for healing.
- Exercise – Your chiropractor can guide you through exercises and stretches to improve flexibility, strengthen the muscles supporting your spine, and reduce pressure on the affected disc.
- Medications – Over-the-counter pain relievers can help manage mild to moderate pain. In more severe cases, your doctor might recommend prescription medications or even corticosteroid injections to reduce inflammation.
Hot and Cold Therapy – Alternating between heat and cold packs can provide relief by reducing swelling and relaxing tense muscles. - Lifestyle Changes – Maintaining a healthy weight, practicing good posture, and incorporating regular exercise into your routine can prevent further strain on your spine and lower your risk of future disc problems.
- Chiropractic treatments – A bulging disc is one of the most common reasons people visit a chiropractor. Chiropractic care often focuses on spinal adjustments to improve alignment and relieve pressure on the affected nerves, providing pain relief and promoting long-term spinal health.
For the most serious cases, where non-invasive treatments don’t provide relief, surgical options may be considered. These procedures aim to remove the portion of the disc pressing on the nerve or, in rare cases, replace the damaged disc entirely.
How a Chiropractor Can Help
If you suspect you suffer from a bulging disc, a chiropractor will examine your spine to determine the exact cause of your issues. Once a chiropractor determines what is causing the herniated disc, they will work on realigning the spine to relieve pressure and restore your natural biomechanics.
The goal of chiropractic treatments is to provide short-term pain relief, do away with numbness, and improve your range of motion in the short term, as well as treat the root causes to provide long-term solutions. Besides the treatment itself, an experienced chiropractor will explain the preventative measures you can take to avoid future back problems.
