Some bulges are good. A bulging wallet means you’re flush with cash. A bulging suitcase means you’re off on holiday. Bulging muscles mean your workouts have paid off.
A bulging disc, on the other hand, is not good news. It might be caused by age-related degeneration or by trauma, but it can cause uncomfortable symptoms. So, what’s going on?
What is a disc?
You have 23 discs in your spine. They’re like small, rubbery cushions that sit between the bony building blocks (vertebrae) of your spine. Each disc has a soft, jelly-ish centre (nucleus) surrounded by a thick elastic coating (annulus).
Your discs do several important jobs, including:
- Absorbing shock
- Allowing movement without sacrificing too much strength
- Protecting the nerves that run throughout your spine.
What’s a bulging disc?
Well, it’s the bad kind of bulge.
A disc may degenerate with age or trauma, bulging beyond its usual boundaries, a bit like a burger that’s too big for its bun. It’s also known as a protruding disc. Some people refer to them as slipped discs, but this is an unhelpful term, because your discs never really slip. Even with a bulging disc, your spine remains stable and is capable of a majority of its functions. In fact, many people have bulging discs naturally, without pain. Some bulges just can’t be helped!
A bulging disc is not the same as a herniated disc. In a bulging disc, the disc itself remains intact, but is spreading beyond its usual place. Visualise it a bit like your stomach after a heavy meal.
A herniated disc goes a step further. The disc tears and its nucleus (disc centre) leaks out through the annulus (outer coating). This still isn’t necessarily cause for panic, a proper assessment is still required to know the impact and severity.
Who’s at risk of a bulging disc?
You’re more likely to develop disc problems if you:
- Are obese
- Are unfit or don’t exercise regularly
- Have poor posture
- Lift heavy loads
- Are getting older.
Symptoms of a bulging disc
If you’ve developed a bulging disc, you may notice symptoms such as back pain that gets worse when you:
- Sit for a long period
- Cough, sneeze, laugh or strain.
If the disc is impacting a nearby nerve, you may experience pain in your extremities (like arms or legs) and this is called radicular pain. If your nerve is a little more impacted and upset, you may develop pins and needles or numbness in your arms or legs; this is called radiculopathy. Sometimes radiculopathy can progress to weakness of the muscles and diminished reflexes. If you experience these symptoms, you should book into physiotherapy or a medical practitioner as a matter of urgency. If in doubt, call 000.
Treatment options for a bulging disc
Your physiotherapist will work with you to develop a treatment plan for your bulging disc that may include:
- Encouraging your body’s natural healing processes
- Managing pain using medications, dry needling, soft tissue massage or taping
- Prescribing bulging disc exercises to strengthen your lower abdominal and core muscles which help to stabilise your back
- Stretches and remedial massage
- Preventing further problems through a biomechanical assessment, ongoing core work, and regular gentle exercise like swimming.
- If required, referring you to the right specialist medical practitioner
