Understanding Chronic Pain: Symptoms, Causes, and Treatment

Chronic pain is pain that persists or recurs for more than 3 months, often continuing beyond the expected healing time of an injury or illness. In Australia, it affects roughly 1 in 5 adults over 45, making it more common than diabetes or heart disease.

In this blog, we are going to break down the symptoms of chronic pain and what actually causes it. Furthermore, we’ll tell you about treatment options that you can opt for in case of chronic pain.

What Are the Symptoms of Chronic Pain?

Chronic pain symptoms go far beyond just “it hurts.” The pain itself can feel different depending on what’s driving it, and it usually brings along a few unwelcome side effects too.

Physical Pain Sensations

Chronic pain rarely feels the same from one day to the next. Here’s what patients most commonly describe:

• Aching or dullness → a steady, nagging discomfort in muscles or joints that never fully switches off.
• Burning or shooting pain → sharp, electric, or stabbing sensations, often a sign the nerves are involved.
• Stiffness and tightness → reduced flexibility, especially first thing in the morning or after sitting still.
• Hypersensitivity → touch, heat, or even light pressure feels far more painful than it should. Doctors call this allodynia or hyperalgesia.

One key characteristic of chronic pain is that it doesn’t follow the usual healing timeline. Acute pain fades as tissue repairs itself. Chronic pain often keeps going even after scans show nothing wrong, because the nervous system itself has changed how it processes pain signals.

It’s Not Just Physical

This is the part people underestimate. Chronic pain rarely stays contained to the body:

• Fatigue that doesn’t improve with rest.
• Sleep disturbances, including trouble falling asleep or waking through the night.
• Mood changes such as irritability, low mood, or anxiety.
• Brain fog, where concentration and short-term memory take a hit.

If you’re ticking several of these boxes, it’s worth getting checked rather than pushing through. Pain that disrupts sleep and mood tends to get harder to manage the longer it’s left untreated.

Types of Chronic Pain

Not all chronic pain behaves the same way, and knowing the type helps guide treatment.

Most patients actually have a mix of these, which is exactly why a one-size-fits-all approach rarely works.

What Causes Chronic Pain?

There’s usually more than one factor at play. Causes of chronic pain generally fall into three buckets: structural, neurological, and lifestyle-related.

Common Physical Causes

• Arthritis and joint damage → cartilage breaks down, and inflammation builds up, leading to ongoing stiffness.
• Spine and disc issues → herniated discs or age-related spinal changes press on nerves and surrounding tissue.
• Nerve damage (neuropathic pain) → faulty signalling in the nervous system creates burning or shock-like pain, even without an active injury.
• Fibromyalgia → widespread pain linked to how the brain processes sensory input, rather than damage in one specific spot.
• Old injuries or surgeries → scar tissue and nerve irritation from a poorly healed fracture, sprain, or operation can flare up years later.

The Nervous System’s Role

Here’s something most blogs skip over: chronic pain isn’t always about ongoing damage. Sometimes the nervous system becomes hyper-alert, a process the Agency for Clinical Innovation NSW Health describes as the nervous system amplifying pain signals well beyond what the original injury would explain. 

Essentially, your brain and spinal cord start treating harmless signals, like a light touch or normal movement, as threats. This is why pain can persist long after tissue has fully healed, and why it can spread beyond the original injury site.

Lifestyle and Psychological Contributors

• Stress and mental health → anxiety and low mood change how the brain interprets pain, often making it feel more intense.
• Poor sleep → disrupted sleep lowers your pain threshold, creating a frustrating cycle.
• Genetics and posture → family history, repetitive strain, and poor ergonomics can all set the stage for chronic issues later on.

Chronic Pain Treatment: What Actually Works

There’s no single fix for chronic pain. The most effective chronic pain management plans combine a few approaches at once, tailored to the person rather than the diagnosis alone.

Medications

• Non-opioid options: Paracetamol and anti-inflammatories (like ibuprofen) help with mild to moderate flare-ups.
• Adjuvant medications: Certain antidepressants and anti-seizure medications are often prescribed off-label to calm nerve-related pain, not because the patient has depression or epilepsy.
• Opioids: Generally avoided for long-term, non-cancer pain due to the risk of dependence and tolerance, a position backed by Healthdirect’s guidance on managing chronic pain. Your GP will only consider this as a short, closely monitored option when nothing else has worked.

Physical and Lifestyle Approaches

• Physiotherapy → guided movement and strengthening to rebuild function without triggering flare-ups.
• Graded exercise → starting small and building tolerance gradually, rather than pushing through pain.
• Pacing daily activities → spreading tasks out instead of doing everything on a “good day” and paying for it for the next three.

Psychological Support

Cognitive behavioural therapy (CBT) and mindfulness-based approaches genuinely help patients reframe how they respond to pain signals. This isn’t about “it’s all in your head.” It’s about retraining a nervous system that’s become overprotective.

Interventional Options

For pain that hasn’t responded to the above, options like targeted nerve blocks, joint injections, or radiofrequency ablation may be considered. These are usually managed through a referral to a pain specialist rather than in general practice.

The goal of chronic pain treatment isn’t zero pain; it’s getting back function, sleep, and quality of life.

Take Control of Chronic Pain with Main Street Medical Centre

You don’t have to just live with ongoing pain, and you don’t need to figure it out alone either. Our GPs at Main Street Medical Centre can assess your symptoms, coordinate the right specialists, and build a chronic pain management plan around your daily life, not the other way around.

For patients managing arthritis, back pain, or other long-term musculoskeletal conditions, our chronic disease management program coordinates care between your GP, physiotherapist, and other allied health providers under one plan. 

As an AGPAL-accredited, GP-owned family practice in Osborne Park, we focus on continuity of care, so you’re not repeating your story to a new provider every few months.

FAQs

What’s the difference between acute pain and chronic pain? 

Acute pain fades as an injury heals, usually within weeks. Chronic pain lasts beyond three months and often continues even after tissue damage has fully healed.

Can chronic pain be cured completely, or only managed? 

Most chronic pain is managed rather than cured, especially once the nervous system is involved. Combined treatment can still reduce pain significantly and, for some, resolve it almost fully.

Is chronic pain recognised as a disability in Australia? 

Not automatically. Chronic pain can qualify under the Disability Discrimination Act if it substantially limits daily activities, depending on the underlying condition and its documented impact.

Why does chronic pain feel worse at night or in cold weather? 

Fewer distractions at night make pain more noticeable, while cold weather tightens muscles and slightly reduces blood flow, increasing stiffness around old injuries and joints.
