10 Common Causes of Back Pain and When to See a Physiotherapist in Mississauga

Back pain is one of the leading reasons people seek healthcare. Whether you’re working long hours at a desk, lifting heavy objects, or simply dealing with age-related changes, back pain can interfere with your daily activities and overall quality of life.

At Fairview Physiotherapy, we help patients throughout Mississauga identify the root cause of their pain and create personalized treatment plans that promote long-term recovery.

In this guide, we’ll explore the 10 most common causes of back pain, symptoms to watch for, and when it’s time to seek professional physiotherapy.

Why Does Back Pain Happen?

Your back is made up of bones, muscles, ligaments, joints, discs, and nerves that all work together to support movement. Pain can occur when any of these structures become irritated, inflamed, injured, or weakened.

Back pain may develop suddenly after an injury or gradually over months or years due to poor posture, repetitive strain, or aging.

1. Poor Posture

One of the biggest contributors to chronic back pain is poor posture.

Sitting for long hours while slouching places extra stress on your spine and surrounding muscles. Over time, this can lead to stiffness, muscle fatigue, headaches, and persistent lower back pain.

Common Signs

  • Rounded shoulders
  • Neck stiffness
  • Lower back discomfort
  • Pain after sitting

2. Muscle or Ligament Strain

Heavy lifting, sudden twisting movements, or overexertion can stretch or tear muscles and ligaments in your back.

This type of injury often causes sharp pain, muscle spasms, and difficulty moving.

3. Herniated or Bulging Discs

The discs between your spinal bones act as cushions.

When a disc bulges or ruptures, it may press against nearby nerves, causing pain that travels into your legs.

Symptoms include:

  • Leg pain
  • Numbness
  • Tingling
  • Weakness

4. Sedentary Lifestyle

A lack of physical activity weakens your core muscles, reducing support for your spine.

People who spend most of the day sitting often experience:

  • Lower back stiffness
  • Tight hips
  • Poor flexibility
  • Muscle weakness

5. Stress and Muscle Tension

Stress doesn’t only affect your mind—it also affects your body.

When you’re stressed, muscles tighten, especially around the neck, shoulders, and lower back, often leading to persistent discomfort.

6. Arthritis

As we age, spinal joints naturally wear down.

Osteoarthritis can cause:

  • Joint stiffness
  • Chronic pain
  • Reduced mobility
  • Swelling

Physiotherapy helps improve joint mobility while reducing pain naturally.

7. Sciatica

Sciatica occurs when the sciatic nerve becomes irritated or compressed.

Pain usually starts in the lower back and travels down one leg.

Symptoms include:

  • Burning pain
  • Tingling
  • Numbness
  • Leg weakness

8. Improper Lifting Techniques

Many people lift objects using their back instead of their legs.

Improper lifting increases pressure on spinal discs and muscles, leading to injury.

Always:

  • Bend your knees
  • Keep the load close
  • Lift with your legs
  • Avoid twisting

9. Poor Sleeping Position

Sleeping on an old mattress or using an unsupportive pillow can place unnecessary strain on your spine.

Proper sleeping posture helps reduce morning stiffness and supports spinal alignment.

10. Previous Injuries

Old injuries that were never fully rehabilitated often return later in life.

Physiotherapy can restore strength, flexibility, and movement while reducing the risk of recurring pain.

When Should You See a Physiotherapist?

While mild back pain often improves within a few days, you should seek professional care if your pain:

  • Lasts longer than one week
  • Keeps coming back
  • Travels down your leg
  • Causes numbness or tingling
  • Makes walking difficult
  • Prevents you from working
  • Interferes with sleep
  • Gets worse over time

Early treatment can prevent long-term complications and speed up recovery.
