Not All Back Pain Comes From Your Back: Understanding Referred Pain

You've had that dull ache in your lower back for a week now. You assume it's from sitting hunched over your laptop all day at your Sydney CBD office — and most of the time, that assumption is right. But sometimes, back pain isn't actually coming from your spine at all. It's what's called "referred pain," and knowing the difference can matter a lot.

What Is "Referred Pain," Exactly?

Referred pain happens when a problem in one part of the body is felt in another. Your organs and your spine share overlapping nerve pathways, so when something's going on internally, your brain can misread the signal as coming from your back or hips instead of, say, your kidneys or digestive system. It's not your imagination playing tricks on you — it's just how your nervous system is wired.

This is one of the first things we screen for during an assessment. Genuine disc-related or mechanical back pain tends to follow predictable patterns: it changes with movement, posture, or position, and it often responds to rest, stretching, or gentle pressure. Referred pain frequently doesn't follow those rules, which is a useful clue.

The Organs That Can Mimic Back Pain

A handful of common culprits show up again and again:

Kidney issues, like infections or kidney stones, often cause a deep, one-sided ache in the mid-to-lower back, sometimes paired with fever, nausea, or changes in urination. Digestive problems, including gallbladder or pancreas trouble, can radiate pain toward the mid-back or between the shoulder blades. In women, reproductive conditions such as endometriosis or ovarian cysts can present as lower back or pelvic pain that flares with the menstrual cycle. And in rarer but more serious cases, cardiovascular issues can refer pain toward the upper back or between the shoulder blades.

None of this is meant to alarm you — the overwhelming majority of back pain we see genuinely is mechanical, coming from the discs, joints, or muscles of the spine. But it's exactly why a proper assessment matters before jumping straight to treatment.

Red Flags: When Back Pain Needs a Doctor, Not Just a Chiropractor

A few signs should prompt a trip to your GP or an emergency department rather than a chiropractic clinic: pain that doesn't change at all no matter how you move or position yourself, fever or unexplained weight loss alongside the pain, pain that wakes you at night for no clear mechanical reason, changes in bladder or bowel control, or pain that comes with chest tightness, nausea, or shortness of breath.

If any of these sound familiar, please don't wait it out — get it checked properly first.

How We Tell the Difference at Complete City Health

Every new patient at our Sydney CBD clinic goes through a thorough history and physical assessment before any treatment plan is discussed. We're asking questions like: does the pain change with movement? Is it worse at a particular time of day? Does it radiate in a pattern that matches a nerve root, or does it feel more diffuse and unrelated to posture? These questions help us build a clear picture of whether we're looking at a spinal issue we can help with, or something that needs a different kind of care — in which case, we'll always point you in the right direction.

When It Really Is Your Spine — And What Helps

The good news is that for the vast majority of CBD workers who come through our doors, the pain really is coming from the spine — often a compressed or irritated disc aggravated by long hours at a desk, poor posture, or repetitive strain. In those cases, spinal decompression therapy can be a genuinely effective, non-invasive way to relieve pressure on the affected disc and give your body room to heal.

The bottom line: your back pain deserves a proper explanation, not just a guess. If something feels off, or you've been managing pain without ever really knowing its source, it's worth getting assessed properly.
