The Myth of the Slipped Disc

If you’ve ever been told you have a “slipped disc,” I have good news for you: Discs don’t slip out of place. They are firmly anchored between your vertebrae to absorb force and distribute load. Sometimes, with trauma, overuse, or the natural aging process, the jelly-like centre of a disc can bulge outward, a bit like squishing a jelly doughnut. This bulge can press on a nearby nerve or cause local inflammation, leading to pain.

If the bulge irritates a nerve, you may feel pain running down your leg (sciatica), known as peripheralisation. If there’s inflammation without nerve compression, you’re more likely to feel pain localised to your lower back. Either way, movement can become restricted and uncomfortable.

The Truth About Discs

The poor intervertebral disc has been villainised for years, leading to unnecessary fear and unhelpful beliefs. In reality, disc bulges are extremely common, and many people over 40 have them without any pain at all. When discs do become painful, most improve with time, movement, and conservative treatment.

Now that you understand what’s really happening with a “slipped” disc, let’s set a few myths straight.

The Myths

Myth #1: The worse the pain, the more damage there must be.

  • Pain is not a direct measure of tissue damage. It’s a complex protective response from your brain to perceived threat. The severity of your pain does not indicate the severity of damage to your disc. A small disc bulge can cause severe pain and a large one might cause no pain at all. Pain alone is not an indicator for surgery.

Myth #2: You should not exercise if you have a bulging disc.

  • When it comes to your spine, motion is lotion! Bed rest and complete avoidance can actually make things worse. Modified movement and gradual loading are the keys to helping your back heal and stay resilient.

Myth #3: Once your disc is bulging it will stay that way forever.

  • In most cases, the bulging portion of the disc gets smaller over time, partially or completely resolving in roughly two-thirds of people within six months.

Myth #4: Most people who have disc problems need surgery.

  • In truth, about 90% of painful disc injuries get better on their own or are well managed with conservative treatment. Surgery is reserved for the few who don’t improve or have significant neurological compromise.

Myth #5: “My dad had a bad back, so that’s why I do.”

  • While there may be some genetic influences on things like disc shape or collagen composition, back pain itself is not inherited. What often is passed down are habits, beliefs, and coping patterns: how we move, lift, rest, and respond to pain. If you grew up watching a parent struggle with back pain, you may have internalised ideas like “my back is fragile” or “I need to protect it.” These beliefs can unconsciously lead to fear of movement, stiffness, and deconditioning, all of which can actually increase the likelihood of pain. BUT you are not destined to repeat your parents’ pain story. With the right information, movement, and support, you can retrain your body and your brain to move with confidence again.

So What Next?

Most people don’t want to wait six months in pain while the disc heals naturally; that’s where conservative care comes in.

Treatment focuses on:

  • Reducing pain and calming the irritated structures
  • Improving movement to restore normal loading
  • Preventing maladaptive compensation patterns that can create new problems later
  • Optimising function

This often includes specific exercises, stretches, and manual therapy, along with short-term use of simple anti-inflammatories or analgesics if needed. Rehabilitation is the next phase, which targets the underlying risk factors (like posture, lifting mechanics, or muscle imbalances) to help prevent recurrence.

In Summary

Disc injuries are far less scary than their reputation suggests. With a little knowledge, consistency, and patience, you can get back to doing the things you love; and often, come out stronger than before! Invest in caring for your spine today, and start building the foundation for your strength tomorrow.

Move Well. Live Well.
