Back pain is one of the most common reasons people seek healthcare—affecting up to 80% of adults at some point in their lives. If you’re dealing with back pain, whether it’s a dull ache that won’t go away, sharp pain with certain movements, or sciatica shooting down your leg, you’re not alone. At Midas Physiotherapy in Oakville, we provide comprehensive, evidence-based treatment for back pain and sciatica, helping you understand your condition, reduce your pain, and get back to the activities that matter to you.
Here’s what’s important to know: most back pain improves significantly with conservative treatment. Despite how frightening back pain can feel—and how debilitating it can be in the moment—the vast majority of episodes resolve without surgery, and physiotherapy is one of the most effective treatments available. Even sciatica, with its distinctive shooting leg pain, typically improves with conservative care.
Modern understanding of back pain has evolved significantly. We now know that imaging findings often don’t correlate with pain—many people with “abnormal” MRIs have no symptoms, while others with significant pain have normal imaging. We also know that staying active is far better than bed rest, and that understanding your pain can actually help reduce it. Our approach incorporates this current evidence to provide treatment that actually works.
For Oakville residents dealing with back pain or sciatica, our Cornwall Road clinic offers expert assessment to identify what’s causing your symptoms and individualized treatment to help you recover.
Understanding Back Pain
The lumbar spine (lower back) consists of five vertebrae (L1–L5) sitting atop the sacrum. Between each vertebra is an intervertebral disc—a tough, fibrous outer ring (annulus fibrosus) surrounding a gel-like center (nucleus pulposus). These discs act as shock absorbers and allow spinal movement. Behind the disc, facet joints connect adjacent vertebrae and guide spinal motion. The spinal canal runs through the center, housing the spinal cord (which ends around L1–L2) and the cauda equina—the bundle of nerve roots that continue below.
Nerve roots exit at each level through openings called foramina, traveling to the legs where they control muscle function and sensation. Multiple muscles and ligaments support the spine—including the multifidus, erector spinae, quadratus lumborum, and psoas—working together to provide stability and control movement.
Types of Back Pain
Mechanical or Non-Specific Low Back Pain
The most common type—accounting for approximately 90% of low back pain cases. “Mechanical” means the pain relates to the structures of the spine (muscles, joints, discs, ligaments) rather than serious pathology like cancer or infection. “Non-specific” means we can’t pinpoint a single structure as the definitive cause—and importantly, we don’t need to identify the exact structure to treat it effectively. Mechanical back pain typically worsens with certain movements or positions and improves with others.
Disc-Related Pain
Intervertebral discs can be a source of back pain through several mechanisms:
- Disc bulge or protrusion: The disc extends beyond its normal perimeter but the outer layer remains intact
- Disc herniation (extrusion): Material from the disc’s center pushes through the outer layer
- Disc degeneration: Age-related changes including loss of disc height and hydration
- Discogenic pain: Pain arising from the disc itself, often with sitting and bending
Important: Disc abnormalities are extremely common in people without back pain. Studies show 30–40% of young adults and 80–90% of older adults have disc abnormalities on MRI with no symptoms. Having a disc bulge or degeneration on imaging doesn’t mean it’s causing your pain.
Facet Joint Pain
The facet joints (zygapophyseal joints) can become painful due to osteoarthritis, inflammation, or mechanical dysfunction. Facet pain typically worsens with extension (arching backward), rotation, and prolonged standing. Pain is usually felt in the lower back, sometimes referring to the buttocks or upper thighs, but rarely below the knee.
Sacroiliac Joint Pain
The sacroiliac (SI) joints connect the sacrum to the pelvis. SI joint dysfunction can cause pain in the lower back, buttock, and sometimes into the groin or upper thigh. It’s often aggravated by activities that stress the joint—prolonged standing, climbing stairs, or transitional movements like getting out of a car.
Muscle-Related Pain
Muscles of the lower back can become painful due to strain (overload injury), muscle spasm (protective tightening in response to injury or pain), trigger points (hyperirritable spots that cause local and referred pain), and deconditioning (weakness contributing to poor spinal support). Muscle involvement is often secondary to other problems—the muscles tighten to protect an injured area.
Understanding Sciatica
Sciatica refers to pain that radiates along the path of the sciatic nerve—from the lower back through the buttock and down the back of the leg. True sciatica involves irritation or compression of a lumbar nerve root (most commonly L4, L5, or S1) that contributes to the sciatic nerve. The term is often used loosely for any leg pain, but true sciatica has specific characteristics.
Characteristics of Sciatica
- Radiating leg pain: Pain travels from the lower back or buttock down the leg, often past the knee
- Dermatomal pattern: Pain follows a specific path corresponding to the affected nerve root
- Leg pain often worse than back pain: A hallmark feature—the leg symptoms predominate
- Neurological symptoms: May include numbness, tingling, or weakness in specific areas
- Worsened by certain positions: Often aggravated by sitting, bending, coughing, or sneezing
What Causes Sciatica?
- Disc herniation: The most common cause—disc material compresses or irritates a nerve root
- Spinal stenosis: Narrowing of the spinal canal or foramina compresses nerve roots
- Spondylolisthesis: Forward slippage of one vertebra on another can compress nerves
- Piriformis syndrome: The piriformis muscle in the buttock irritates the sciatic nerve (less common)
The Good News About Sciatica
Most sciatica improves with conservative treatment. Studies show that 80–90% of people with sciatica from disc herniation improve without surgery, typically within 6–12 weeks. Disc herniations can actually shrink or disappear on their own (spontaneous resorption)—larger herniations are often MORE likely to resorb. Symptoms often improve even before structural changes occur on imaging, because inflammation and nerve sensitivity resolve.
Symptoms of Back Pain and Sciatica
Back Pain Symptoms
- Localized pain: Aching, stiffness, or sharp pain in the lower back
- Movement-related pain: Pain with bending, lifting, twisting, or transitional movements
- Position-related pain: Pain worse with prolonged sitting, standing, or certain positions
- Morning stiffness: Stiffness upon waking that improves with movement
- Muscle spasm: Visible or palpable muscle tightness
- Referred pain: Pain spreading to buttocks or upper thighs (but not typically below the knee)
Sciatica Symptoms
- Radiating leg pain: Sharp, shooting, or burning pain traveling down the leg
- Numbness or tingling: Altered sensation in the leg or foot
- Weakness: Difficulty with specific movements (e.g., foot drop with L5 involvement, calf weakness with S1)
- Pain worse with sitting: Sitting increases pressure on discs and can worsen nerve compression
- Relief with certain positions: Often better with standing, walking, or lying down with knees bent
How We Treat Back Pain and Sciatica
Our approach combines the best available evidence with individualized care tailored to your specific presentation.
Comprehensive Assessment
We begin with thorough evaluation including detailed history of your symptoms, onset, aggravating and relieving factors; physical examination including range of motion, strength, neurological testing, and special tests; movement assessment to identify patterns and contributing factors; screening for red flags that might require referral; and understanding your goals and what’s most important to you. This assessment guides an individualized treatment plan.
Education and Reassurance
Understanding your back pain is therapeutic. We explain what’s likely causing your symptoms, why the prognosis is generally good, and what you can do to help yourself. Research shows that reassurance and education reduce fear-avoidance beliefs—which are strong predictors of poor outcomes. Knowing that most back pain improves, that imaging findings often don’t correlate with symptoms, and that your spine is strong and capable of healing helps you engage actively in recovery.
Manual Therapy
Hands-on treatment can reduce pain, improve mobility, and facilitate your ability to exercise and move:
- Spinal mobilization and manipulation: Restoring joint mobility and reducing pain
- Soft tissue therapy: Addressing muscle tension, trigger points, and fascial restrictions
- Neural mobilization: Techniques to improve nerve mobility when neural tension contributes to symptoms
- Muscle energy techniques: Using muscle contractions to improve joint mobility
Manual therapy is an adjunct to active treatment—it helps create a window for you to move and exercise more comfortably.
Exercise Therapy
Exercise is the cornerstone of back pain treatment—more effective than many passive treatments and with lasting benefits. We prescribe:
- Directional preference exercises: Many people have a direction of movement that reduces or centralizes symptoms (McKenzie approach)
- Core stability training: Strengthening the deep stabilizers (transversus abdominis, multifidus) that support the spine—not traditional crunches
- General strengthening: Building strength in the back, hips, and legs
- Flexibility work: Addressing tightness in hip flexors, hamstrings, and other areas that affect spinal mechanics
- Aerobic conditioning: Walking, cycling, swimming—general activity that promotes healing and reduces pain sensitivity
- Graded exposure: Gradually returning to feared or avoided movements and activities
Pain Management Strategies
We teach strategies to manage symptoms while you recover:
- Positioning: Finding positions that reduce symptoms (e.g., lying with knees bent)
- Activity modification: Temporarily adjusting activities without complete avoidance
- Pacing: Balancing activity with rest, avoiding the boom-bust cycle
- Heat or ice: Whichever provides relief—both are safe
- Flare-up management: What to do when symptoms temporarily worsen
Lifestyle and Ergonomic Guidance
We address factors in your daily life that may contribute to symptoms: workstation setup for those who sit at desks, lifting technique education, sleeping positions, movement habits throughout the day, and strategies for prolonged sitting or standing. The goal isn’t rigid “perfect” posture but incorporating variety and movement.
Frequently Asked Questions
- Do I need an X-ray or MRI for my back pain?
Usually not initially. Imaging is indicated when red flags are present (signs of serious pathology), symptoms aren’t improving as expected, or surgery is being considered. For most back pain, imaging doesn’t change treatment and often reveals incidental findings that don’t correlate with symptoms—which can actually increase anxiety. We’ll recommend imaging if clinically indicated.
- My MRI shows disc degeneration/bulging. Is that causing my pain?
Not necessarily. These findings are extremely common in people without pain—studies show 30–40% of young adults and 80–90% of older adults have disc abnormalities on MRI with no symptoms. Your symptoms may correlate with imaging findings, but they often don’t. Treatment based on clinical presentation is often more effective than treatment based on imaging alone.
- Should I rest until my back feels better?
No. Prolonged rest actually delays recovery. Current guidelines recommend staying as active as possible within pain limits. Walking, gentle movement, and continuing modified daily activities promote healing better than bed rest. Complete rest leads to deconditioning and can make recovery harder. Brief periods of rest during acute flare-ups are fine, but prolonged inactivity is harmful.
- Will I need surgery?
Most likely not. The vast majority of back pain and sciatica improves with conservative treatment. Surgery is typically only considered for cauda equina syndrome (emergency), progressive neurological deficits, or severe symptoms not responding to 6–12 weeks of adequate conservative treatment. For sciatica, research shows similar outcomes at 1–2 years whether people have surgery or conservative care—surgery may provide faster relief but doesn’t change long-term outcomes.
- What positions help relieve back pain?
This varies by individual. Common relieving positions include lying on your back with knees bent and feet flat, lying on your side with a pillow between your knees, and for some, lying face-down or with a pillow under your stomach. Generally, positions that maintain a neutral spine or slight flexion (rounding) are more comfortable for disc-related pain, while extension (arching) often helps facet-related pain. We help identify your specific directional preference.
- How long will my sciatica last?
Most sciatica improves significantly within 6–12 weeks with conservative treatment. Some people continue improving over 3–6 months as the underlying disc herniation naturally shrinks. Symptoms often improve before imaging changes—the inflammatory response and nerve sensitivity resolve first. Recovery isn’t always linear; fluctuations are normal. About 80–90% of people with sciatica from disc herniation improve without surgery.
- Is my spine damaged?
Usually, no. The spine is a remarkably strong and adaptable structure. Even disc herniations represent a part of the disc pushing outward, not permanent structural damage—and most herniations naturally resorb. Terms like “degenerative disc disease” and “bulging disc” sound alarming but describe normal age-related changes seen in most adults without symptoms. Pain doesn’t necessarily mean damage, and your spine is capable of healing.
- Can I prevent back pain from coming back?
You can significantly reduce recurrence risk. Regular exercise (especially core strengthening and general conditioning), maintaining a healthy weight, staying active in daily life, managing stress, and using good body mechanics all help. About 30% of people experience recurrence, but those who maintain an exercise program have lower rates. Complete prevention isn’t always possible, but you can reduce frequency and severity.
- What’s the difference between referred pain and sciatica?
Referred pain from the back can travel to the buttock and upper thigh without involving nerve compression—it typically doesn’t go below the knee, doesn’t cause neurological symptoms (numbness, tingling, weakness), and is felt as a diffuse ache. True sciatica involves nerve root compression or irritation, typically travels past the knee following a specific nerve path (dermatomal pattern), and may include neurological symptoms.
- Is it safe to exercise with back pain?
Yes, and it’s beneficial. Exercise is the most strongly supported treatment for back pain. Start with gentle movement within your comfort range and gradually increase. Some discomfort during exercise is normal and doesn’t mean you’re causing harm. Avoiding all activity due to fear of pain can actually perpetuate the problem. We’ll guide you on appropriate exercises for your specific situation.
- What about core strengthening and posture?
Core strengthening is beneficial for back health, but not the way it’s often portrayed. We focus on training the deep stabilizers (transversus abdominis, multifidus) rather than surface muscles (rectus abdominis). As for posture, there’s no single “perfect” posture—variety is key. Prolonged positioning in any posture can cause discomfort. We emphasize movement variety and avoiding sustained positions rather than rigid postural rules.
- Do I need a referral to see you?
No. In Ontario, you can access physiotherapy directly without a doctor’s referral. We’ll assess your condition, begin treatment, and recommend imaging or specialist referral if indicated. If you’ve already had imaging, bring your reports—but treatment can begin based on clinical findings even without imaging.
