A lumbar disk herniation — also called a slipped disc, ruptured disc, or disc bulge — is one of the most common causes of lower back pain and leg pain (sciatica). It occurs when the soft inner material of an intervertebral disc pushes through the tough outer layer, pressing on nearby spinal nerves.
What is Lumbar Disk Herniation?
The lumbar spine (lower back) bears most of your body's weight and is subject to significant mechanical stress. Discs act as shock absorbers between vertebrae, but with age, injury, or repetitive stress, the outer fibrous ring can weaken and allow the inner gel-like nucleus to protrude. This herniation can compress or irritate adjacent nerve roots, causing pain, numbness, and weakness that radiates into the legs.
Common Symptoms
- Sharp or aching lower back pain, often on one side
- Radiating pain, numbness or tingling down the leg (sciatica)
- Muscle weakness in the hip, thigh, calf or foot
- Pain that worsens with sitting, bending forward, or coughing
- Pain relief when lying down or walking
- Difficulty with daily activities such as standing, walking, or lifting
Common Causes
- Age-related disc degeneration and loss of disc hydration
- Sudden heavy lifting using improper body mechanics
- Repetitive twisting or bending movements
- Prolonged sitting or sedentary work habits
- Excess body weight increasing lumbar load
- Trauma or injury to the spine
- Genetic predisposition to disc disease
Treatments at Woodbridge Rehabilitation Centre
Our multidisciplinary team creates a personalized treatment plan based on your specific presentation, health history, and goals. The following therapies may be recommended individually or in combination.
Chiropractic Adjustments
Spinal manipulation and mobilization may help reduce pain and improve mobility for some people with disc-related low back pain, as part of a broader plan that includes exercise. Techniques are selected after a thorough orthopedic and neurological examination and modified to suit your presentation.
Physiotherapy
A structured rehab program — which may include stabilization exercises, the McKenzie method and neural mobilization — aims to reduce pain, improve function and strengthen supporting muscles to lower the risk of recurrence.
Softwave Therapy
Softwave (low-intensity, unfocused shockwave therapy) may be considered as an adjunct for persistent low back pain, applied to the surrounding muscles and soft tissues. Research on shockwave therapy for disc-related pain is still limited, and it does not reposition a disc or remove pressure from a nerve. Your practitioner will discuss whether it is appropriate for you.
Acupuncture
Acupuncture may be offered as a complementary option for short-term pain relief alongside exercise and manual therapy. Evidence for its effect on disc-related pain is mixed.
Therapeutic Modalities
Traction, IFC and TENS may be used for short-term symptom relief in the early phase. Evidence for these passive modalities is limited, so they are used alongside — not in place of — active rehabilitation.
When to Seek Urgent Care
Contact your physician promptly, or call 911 or go to the nearest emergency department, if you experience any of the following:
- Loss of bladder or bowel control, or numbness in the groin or inner thighs (possible cauda equina syndrome — go to the emergency department immediately)
- Progressive leg weakness or foot drop
- Back pain following significant trauma, such as a fall or car accident
- Fever, unexplained weight loss, a history of cancer, or severe constant pain at night
