Lower Back Pain: Causes, Relief, and When to Worry

You're Not Alone

Lower back pain is one of the most common reasons Canadians visit a doctor or miss work. The reassuring news: the vast majority of cases are "non-specific," meaning there's no serious underlying disease, and most improve within a few weeks.

Common Causes

  • Muscle or ligament strain from lifting, twisting, or poor posture
  • Prolonged sitting, especially with weak core muscles
  • Disc-related issues that can press on nerves
  • Age-related changes in the spine

What Actually Helps

Modern guidance has shifted away from bed rest. Staying gently active is now the cornerstone of recovery:

  1. Keep moving. Light activity like walking speeds recovery; prolonged bed rest can make things worse.
  2. Use heat or cold. Both can ease discomfort — use whichever feels better.
  3. Try over-the-counter pain relief like ibuprofen or acetaminophen as directed.
  4. Gentle stretching and strengthening. Building core strength helps prevent recurrence.
  5. Improve your setup. Adjust your chair, screen height, and lifting technique.

Physiotherapy is very effective for persistent back pain. Some provincial plans offer limited coverage, and many extended health benefits include it.

Red Flags — See a Doctor Promptly

Most back pain is harmless, but seek care quickly if you have:

  • Numbness or tingling in the groin or inner thighs
  • Loss of bladder or bowel control
  • Weakness or numbness in a leg
  • Pain after a significant fall or accident
  • Unexplained weight loss, fever, or night pain
  • A history of cancer

These can signal conditions that need urgent attention — the first two especially warrant an immediate ER visit.

Preventing the Next Episode

Strong core muscles, regular movement, good lifting technique (bend the knees, keep the load close), and avoiding long stretches of sitting all reduce your odds of a repeat. If your work involves heavy lifting or long sitting, build short movement breaks into your day.
