What is a disc bulge?
Did you know that almost 80% of the global population experience an episode of low back pain at some point in their life, with degenerative disc disease and lumbar disc herniation (disc bulge) being the most common.
A disc bulge is also known as a bulging disc, slipped disc, or disc protrusion and is a condition during which a nucleus pulposus is displaced from intervertebral space. This can happen in the lumbar (low back), thoracic (mid back) or cervical (neck) spine.
Here, the side and cross sectional views of a herniated disk are shown. In a herniated disc the soft, jelly-like centre of the disc can push all the way through the outer ring (source). This can cause pain, and may or may not press on the adjoining nerve, which can cause pain to travel down our thigh or leg, and even down to the inside or outside of our feet.
Should I be concerned, will my disc bulge get better?
Most occurrences of a bulging disc (disc herniation) resolve with conservative treatment and resolve within as little as two to eight weeks. 85 to 90% of cases will resolve within this time-frame and without substantial medical intervention.
It can be scary when you have back pain, or have been informed you have a bulging disc, but there is really good evidence to show that it will get better, without the need for surgery.
Disc Bulges - a normal part of ageing process??
Recent evidence has found that disc bulges and degenerative back conditions are a normal part of ageing, just like grey hair and wrinkles on your skin. We should not fear them as being a life sentence, rather just a normal part of life. Furthermore, they don't always result in pain.
The study below shows that when 20 year olds WITHOUT back pain were scanned, 37% of them had disc degeneration, and 30% of them had a disc bulge. However, with increasing age, this number continues to increase, and in our 60's 88% of people WITHOUT BACK PAIN were shown to have disc degeneration, and 69% WITHOUT BACK PAIN shown to have a disc bulge.
What should I do?
Listen to your body and stay as active as you can within your own pain limits. You may find paracetamol helpful in settling your pain in the initial stages.
You may find that sitting is better than standing, or vice versa, or standing and arching your back a little, or maybe even laying down and swaying your bent knees gently from side to side. Whatever movement you find that is comfortable for you, and your pain remains below a 2 out 10, continue to do.
As your back starts to feel better you may be able to go for some walks, or extend your walks. Backs love movement, and the latest research now tells us that rest is not the best remedy. Deep breathing has also shown to be beneficial in relaxing the musculature of the back, helping to decrease pain.
What are the long term solutions for disc bulge and back pain?
Following on from the initial recovery phase, an essential part of helping back pain is strengthening and this is what Exercise Physiologists are the experts at! If we can help to strengthen your back, it is less likely that physical load will irritate it, this means that you have a decreased chance of recurrence and less severity of symptoms of future episodes.
We now know that pain is multifactorial, this means there are multiple aspects that affect our pain, including psychological and social stressors, nutrition, sleep and physical aspects. We can help to assess your pain and help you to understand your pain, and the things you can do it decrease pain, and improve your strength to help you to live an active life.
Discs respond to load and like getting stronger, just like muscles. It has been found that in people who run or lift weights, that their discs are stronger, fatter and healthier!! What a great reason to exercise!!
We'd love to help you with your back pain!!

Regular stretching enables muscles to maintain flexibility, strength and overall health. This promotes a full range of movement at our joints and reduces the chance of muscles becoming tight and shortening. This can decrease the strength of the muscle and reduces the muscles ability to fully lengthen and extend when needed. That increases the risk of joint pain, muscle damage and strains.
How do I start stretching?
Child’s Pose = Start by kneeling on the ground with your knees and feet together. Reach your arms out long in front of you and lower your chest to your knees and your head to the ground. Try and reach as far as possible whilst simultaneously reaching your bottom back to your sit on your heels. Think about elongating your spine as much as possible.
Cat and Cow Stretch = Start with all fours on the ground, your knees sitting underneath your hips and hands underneath your shoulders. Begin arching your spine up towards the ceiling by tucking your tail bone between your legs and folding your neck so that your head is between your arms, looking back towards your knees. Then switch the pose to curve the spine inwards and turn your tail bone up towards the ceiling and move your head to look up and straight ahead. Continue to move through spinal flexion and extension.
Hip Twist = Lie on your back with your knees bent and feet on the floor, and move your arms out wide to also lay on the floor. Keeping your knees and feet together try moving your knees over to the left of your body whilst turning your head to look out towards your right arm. Then switch this movement to move your knees to the right of your body and turn your head over towards your left arm. Continue to move from side to side.
Knee to Chest Stretch = Lie on your back with both legs extended out straight. Keep your left leg straight and draw your right knee in towards your chest, interlocking your hands behind your thigh or at the top of your shinbone. Switch legs extending your right leg back out and pulling your left knee into your chest. Focus on lengthening through your spine and avoid lifting your hips.

What is the thoracic spine?
The spine is made of 5 different sections being the cervical, thoracic, lumbar, sacrum and coccyx. The thoracic spine starts at the bottom of the neck and ends at the abdomen and is the longest section of the entire spine. The thoracic spine consists of 12 vertebrae stacked on top of each, called T1 down to T12. These vertebrae support the neck, rib cage, connecting joints and soft tissues along with blood vessels and nerves.
What is the Thoracic spine’s role in the body?
The thoracic spine is crucial in supporting and stabilising the rib cage which protects all of our vital organs underneath, including our lungs and heart.
It also protects the spinal cord which sends all messages and signals throughout the entire body. The spinal cord travels from the brain, down through the vertebrae before it branches off into smaller bundles in the lumbar portion of the spine.
What kind of movement does it produce?
The thoracic spine is not as mobile as the neck and lumbar spine and it is quite limited in forward and backward movements at the top vertebrae. Although the thoracic spine can produce more rotational movement within the top few vertebrae to help twist our chest and shoulders.
Common causes of thoracic spine pain?
There can be many possible causes for upper back/ thoracic pain but some of the most common include;
Initially an increased range of movement through the thoracic spine is important to ensure that the spine can move freely without restriction. This may be done by lengthening out the muscles through the front of your chest and shoulders to enable a more upright posture to return. Increasing strength through the thoracic, lumbar and cervical spine will also assist in developing endurance to maintain an upright posture, preventing pain from returning in the future. Each case is assessed and treated individually to determine the best approach for each client.
