What is a Bulging Disc?
A bulging disc is an unhealthy condition where the spinal discs shift away from their normal position. A spinal disc consists of a hard casing with a liquid-like center. When these spinal discs change their position, swelling occurs in the fluid-like material at the weakest section of the disc's shell. This swelling is also known as herniation or a protruding disc.
What is the Use of a Spinal Disc?
These discs are present between the vertebrae and serve two primary purposes:
- Act as a shock absorber
- Protect the spinal tissue and bone from damage
- Facilitate easy movement
Symptoms: How Do You Know if You Have a Bulging Disc?
Depending on the severity, the symptoms of a bulging disc include:
- Mild tingling
- Numbness
- Moderate to severe pain
There are two stages of bulging discs, and the symptoms of these stages vary:
Pre-Herniation:
Before the disc extends to the stage of herniation, a case of a bulging disc may go unnoticed because there may or may not be any pain. Symptoms typically appear when the issues become too severe, making it difficult to manage.
Post-Herniation:
The symptoms of a bulging disc post herniation include:
- Tingling or numbness: in the fingers, hands, arms, neck, or shoulders, indicating a bulging disc in the cervical area.
- Aching: in the feet, thighs, buttocks, and lower spine, indicating problems in the lower back.
- Loss of strength: while holding or lifting things.
- Difficulty walking.
Alert: Post-herniation symptoms could be life-threatening; hence, if you notice these, you should consult your doctor immediately.
Complications if a Bulging Disc is Left Untreated:
Complication | Symptom and Characteristics |
---|---|
The sciatic nerve is affected | Sensations are present in only one leg. |
Bulging disc compresses the nerves that control the bladder | Bladder incontinence or loss of bladder control. |
Mid-spine bulging disc | Pain in the upper back that goes up to the stomach or chest. |
Symptoms associated with a bulging disc may go unnoticed for years, and the risk of complications increases over time. Hence, if you notice the slightest discomfort that may indicate a bulging disc, you should talk to your healthcare provider.
What Causes a Bulging Disc?
Common causes of a bulging disc include:
- Inactive lifestyle and unhealthy habits like smoking
- Injury or frequent heavy lifting
- Weak back muscles increasing the risk of sudden herniation
- Trauma or accident
- Bad posture while sleeping, standing, or exercising
- Obesity
- High-contact sports
- Not using proper running shoes
- Everyday activities that strain the back, such as vacuuming or feeding your pet
How to Diagnose a Bulging Disc?
While investigating the cause of your bulging disc, your physician will ask you about:
- Your lifestyle
- The physical activities you regularly perform
Based on the preliminary investigation, your doctor may recommend the following medical imaging procedures for detailed and accurate analysis:
- X-ray
- CT scan
- MRI scan
The results of these procedures will help diagnose the disorder causing the bulging disc and its complications, such as:
- Lumbar Stenosis: Narrowing of the lower spine's open spaces, leading to pain, tingling, and weakness in the buttock, leg, and foot.
- Spinal Stenosis: Compression on the nerve caused by a herniated disc, bone spur, or narrowing of the spine, also known as sciatica, causing inflammation, pain, and numbness in the affected leg.
- Disc Herniation: An age-related disorder where the outer ring degenerates over time, leading to inflammation and intense pain.
Treatments for a Bulging Disc
Once diagnosed, immediate self-help remedies include:
- Adjusting posture while sleeping, sitting, and standing to minimize strain on the back
- Exercising to reduce obesity, a major trigger factor for bulging discs
- Physical therapy to strengthen back muscles and regain full range of motion
Ways to manage and reduce pain before complications become life-threatening include:
- Over-the-counter anti-inflammatory medications
- Heating pads
- Ice packs
- Exercise
- Massage therapy
If the condition becomes extreme, your doctor may recommend surgery, although surgical interventions are rare.
Physical Treatments for a Bulging Disc
Your physiotherapist may recommend the following exercises:
Piriformis Stretch:
- Lie on your back with both feet flat on the surface and both knees bent.
- Hold the right bent knee with your left hand and pull it across your body towards the left shoulder.
- Hold the stretch for at least 20 seconds and then return the right knee to the original bent position with feet flat on the surface.
- Repeat for the left leg.
Spinal Extension:
- Lie on your stomach on a mat with legs straightened out.
- Keep your elbows on the ground and slide your pelvis, hips, and shoulders down in a relaxed position.
- Lift your upper back while pressing your hips into the mat, keeping your head and neck in a neutral position.
- Hold for 30 seconds, then lower to the beginning position.
- Repeat for 3 sets of 30 seconds each.
Isometric Gluteus Medius Strengthening Exercise:
- Lie on one side with the Gluteus medius muscle you are trying to exercise on the upside.
- Place a belt around both ankles.
- While keeping both legs straight at the knee, lift the top leg straight until there is tension on the belt.
- Hold this contracted position for 5 seconds and then slowly bring your leg back down.
- Repeat 10 times.
Figure Four Stretch:
- Lie on your back with legs bent at the knee and feet flat on the ground.
- Place your right ankle on the left knee.
- Hold the back of your left leg and gradually pull it towards your chest until you reach a comfortable stretch, feeling it in the glutes and hip.
- Repeat for the other leg.
Strengthening Exercise:
- Lie on your back on a flat surface with a pillow under your hips.
- Slowly lift your leg straight up with a 90° angle at the knee.
- Hold for 5-6 seconds and try to do 5 repetitions.
Hip Flexion:
- Lie on your back and gently pull one knee towards your chest while keeping your back flat.
- The opposite thigh can slide to the edge, but the pulled thigh should not move away from the midline.
- Hold for 30 seconds and try to do 2 repetitions with each leg.
Single Knee to Chest:
- Bend your leg at the knee and pull it into your chest until you feel a comfortable stretch in your lower back and hip joint.
- Avoid pulling with a jerk or beyond a comfortable position to prevent overstretching muscles.
- Hold for 15 seconds and repeat 5-10 times for both legs.
Iliotibial Band Stretch:
- Stand upright and cross your hurting leg behind your opposite leg.
- Bend your upper body away from the hurting leg until you feel a stretch across the affected Iliotibial band.
- Hold for 30 seconds and repeat for 5 sets.
Bridge Exercise:
- Lie flat on your back with legs bent at the knee and hands by your side.
- Place your feet flat on the surface under the knee.
- Contract your abdominal and buttock muscles and gently push your lower back into the ground.
- Lift your pelvis in the air by pushing the heels into the floor, forming a straight line with your upper body and thighs.
- Hold for 5 seconds, then gradually lower your body.
- Repeat 8-10 times.
'Cat-Camel' Exercise:
- Kneel on your fours - hands and knees, with hands directly under your shoulders and knees spread shoulder-width apart.
- Round your upper back in a curve, pressing your shoulders forward, holding this 'cat' position for 15 seconds.
- Slowly make a downward curve by arching your back, looking at the ceiling in this 'camel' position for 15 seconds.
- Repeat for 5 sets of cat and camel positions.
Forearm Plank:
- Lie on your stomach with forearms parallel to the surface.
- Tighten your core and lift your body like a pushup, balancing on your forearms and toes.
- Hold for at least 20 seconds, aiming for 30 seconds eventually.
- Try to do 2-5 sets, keeping your back straight to engage your core effectively.
Fastest Way to Cure Cervical Pain:
Your physiotherapist may recommend electrical therapy:
Ultrasonic Therapy:
- Uses ultrasound for deep healing of affected tissues, increasing blood circulation, and rapidly contracting and expanding microscopic gas bubbles around injured tissues.
- Benefits include faster healing, better pain management, and regaining lost range of motion.
Hot Pack Application:
- Useful for managing injury-related pain and stiffness.
- Consult your physiotherapist to know when to start using hot packs, typically recommended after the first week of treatment.
- Heat treatment helps by increasing blood flow in the affected area and relaxing muscles, making it easier to stretch them and reducing pain.
