Have you been told you have a slipped disc?
If so, you’re not alone. One of the most common things we hear at Reliable Spine is: “My doctor says I have a slipped disc.” It’s a phrase that’s been used for decades, but it paints an inaccurate picture of what’s actually happening in your spine.
The term “slipped disc” suggests that something has popped out of place and might need to be pushed back in. That sounds alarming, and it causes a lot of unnecessary worry.
In reality, discs don’t slip. They don’t fall out, roll away, or move between your vertebrae like a coin sliding off a table. The truth is far less dramatic, and understanding what’s actually happening can be the first step toward recovery.
What is a spinal disc?
Between each bone (vertebra) in your spine sits a disc. Think of it like a jam doughnut: there’s a tough, fibrous outer layer (the annulus fibrosus) and a softer, gel-like centre (the nucleus pulposus).
These discs serve three important purposes:
- They act as shock absorbers when you walk, run, or jump.
- They allow your spine to bend and twist.
- They create space between the vertebrae so nerves can exit the spinal canal without being compressed.
Your discs are firmly attached to the vertebrae above and below. They cannot “slip” out of position.
So what actually happens?
Over time, through injury, repeated strain, poor posture, or simply the ageing process, the outer fibres of the disc can weaken. When enough of these fibres break down, the softer inner material can push outward.
This is what we call a disc bulge (sometimes referred to as a disc herniation or disc protrusion, depending on the severity).
Here’s a simple way to think about it: imagine squeezing that jam doughnut from one side. The jam doesn’t “slip” out, it bulges through a weak point in the outer layer. That’s essentially what happens in your spine.
What’s the difference between a bulge, herniation, and protrusion?
These terms are often used interchangeably, but there are clinical distinctions:
| Term | What it means |
|---|---|
| Disc bulge | The disc extends beyond its normal boundary but the outer wall remains intact. Often widespread and may affect a large portion of the disc’s circumference. |
| Disc protrusion | A focal (localised) extension of disc material where the base of the protrusion is wider than the part that extends outward. The outer fibres may be intact or partially torn. |
| Disc herniation (extrusion) | Disc material has broken through the outer fibres. The displaced material may be larger than the neck connecting it to the disc. |
| Sequestration | A fragment of disc material has separated entirely and is now a free-floating piece in the spinal canal. |
Regardless of the terminology, what matters most is whether the displaced disc material is pressing on a nerve or causing inflammation in the surrounding area.
Common symptoms of a disc bulge
Depending on which level of the spine is affected and whether a nerve is involved, you may experience:
- Lower back pain that worsens with sitting or bending forward
- Sciatica: pain travelling into the buttock, thigh, or leg
- Numbness or tingling in the leg or foot
- Muscle weakness in the affected leg
- Pain that increases when coughing, sneezing, or straining
- Difficulty standing up straight after bending
- A feeling of stiffness first thing in the morning
For cervical (neck) disc bulges, symptoms may include neck pain, headaches, or pain, tingling, or weakness travelling into the arm or hand.
Do all disc bulges cause pain?
No. This is one of the most important points to understand.
Research has consistently shown that many people have disc bulges on MRI without any symptoms at all. A well-known study found that around 50% of people over the age of 40 have disc bulges visible on imaging, yet feel perfectly fine.
This means that having a disc bulge on a scan does not automatically explain your pain. The critical question is: does the location and size of the bulge match your symptoms and clinical findings?
That’s why a thorough hands-on assessment is essential before jumping to conclusions based on imaging alone.
How can chiropractic care help?
At Reliable Spine, we begin every case with a detailed consultation and examination. This includes:
- A full medical history
- Orthopaedic testing
- Neurological assessment (reflexes, sensation, muscle strength)
- Movement analysis
- Discussion of imaging results, if available
Once we understand the likely source of your symptoms, we create a treatment plan tailored to your specific needs. This may include:
- Chiropractic adjustments: to restore movement and reduce mechanical stress on the affected segment.
- Spinal decompression therapy: gentle, controlled traction to reduce pressure on the disc and surrounding nerves.
- Rehabilitation exercises: targeted strengthening and mobility work to support long-term recovery.
- Lifestyle and ergonomic advice: practical changes to reduce strain on your spine during daily activities.
What to expect at your first visit
Your first appointment at Reliable Spine typically lasts 45 to 60 minutes. We’ll take time to listen to your story, perform a comprehensive examination, and explain our findings in plain language.
If we believe chiropractic care can help, we’ll outline a clear treatment plan with realistic expectations. If we feel your case requires further investigation or a referral, we’ll tell you that too.
Frequently Asked Questions
Can a disc bulge heal on its own? Yes. Many disc bulges improve over time, especially with appropriate conservative management. The body has a remarkable ability to reabsorb disc material and reduce inflammation when given the right environment to heal.
Is surgery always necessary for a disc bulge? No. The majority of disc bulges respond well to conservative treatment. Surgery is typically reserved for cases involving significant neurological compromise or when symptoms have not improved with appropriate non-surgical care.
How long does recovery take? This varies depending on the severity of the bulge, how long you’ve had symptoms, your general health, and how well you respond to treatment. Most patients notice meaningful improvement within 4 to 8 weeks of consistent care.
Should I rest completely if I have a disc bulge? Prolonged rest is generally not recommended. Staying gently active and following a structured rehabilitation programme tends to produce better outcomes than bed rest.
Can I exercise with a disc bulge? Often yes, but the type and intensity of exercise matters. Your chiropractor can guide you on which movements are safe and which to avoid during the recovery phase.
