Chronic Pain
Chronic Pain: Why Does It Still Hurt When the Scan Looks Normal?
In short: Chronic pain is pain that persists beyond about three months — past the point where tissues would normally have healed. It is real, and it is not “in your head.” In long-standing pain, the nervous system itself becomes more sensitive, so pain can continue even when scans look normal or an injury has healed. Because of this, the most effective treatment is rarely a single injection or operation, but a combined approach: movement, pain education, sleep, targeted treatments and psychological support working together.
Key points
- Chronic pain is pain lasting longer than about three months, and it is a condition in its own right.
- Pain does not always equal damage. The nervous system can become sensitised, producing real pain without ongoing tissue injury.
- A normal scan does not mean the pain is imagined — it means the answer lies elsewhere.
- Scan findings such as disc bulges and degeneration are common in people with no pain at all.
- The most effective management combines several approaches rather than searching for one single fix.
- Gradually returning to movement is one of the most powerful treatments, even though it can feel counterintuitive.
⚠ Some pain still needs urgent assessmentChronic pain is common and usually not dangerous, but certain features need prompt medical review: unexplained weight loss, fever or night sweats, pain that is severe and unremitting at night, a history of cancer, new weakness or numbness, loss of bladder or bowel control, or saddle numbness. These are not typical of ordinary chronic pain and should be assessed without delay. |
What is Chronic Pain?
Chronic pain is pain that persists for longer than about three months. It may begin with an injury, an operation or an illness, or it may start without any clear trigger — and it can continue long after the original problem has healed.
The distinction from acute pain is important. Acute pain is a useful alarm signal warning of tissue damage. Chronic pain is better understood as an alarm system that has become oversensitive — it keeps sounding even when the original threat has passed. That is why treating chronic pain like a prolonged version of acute pain, by searching endlessly for damage to fix, so often disappoints.
Why does it still hurt when my scan is normal?
Because pain is produced by the nervous system, not simply by tissue damage. In persistent pain, the nerves and spinal cord become more sensitive — a process called central sensitisation — so ordinary signals are amplified and interpreted as painful. The pain is entirely real; the source is the sensitised system rather than visible damage.
It is also worth knowing how common scan findings are in people without any pain. Disc bulges, degenerative changes and rotator cuff findings appear frequently in people who feel completely well, and their prevalence rises with age. This means a scan finding is not automatically the cause of your pain — and, conversely, a clear scan does not mean nothing is wrong. Understanding this often relieves a great deal of anxiety, and anxiety itself amplifies pain.
Does chronic pain mean I am causing damage when it hurts?
Usually not. In persistent pain, hurt and harm become uncoupled — an activity can be painful without causing any tissue damage. This is one of the most important things to understand, because fear of damage leads to avoiding movement, and avoidance tends to make pain worse over time.
Long-term avoidance causes deconditioning, stiffness and loss of confidence, all of which increase sensitivity and pain. Breaking that cycle is central to recovery. This does not mean ignoring pain or pushing through it recklessly; it means gradually and confidently reintroducing movement in manageable doses, so the nervous system learns that activity is safe again.
What conditions come under chronic pain syndromes?
The term covers a range of conditions in which persistent pain is the main problem, including chronic low back and neck pain, fibromyalgia, complex regional pain syndrome, persistent post-surgical pain, and long-standing tendon or joint pain that has not settled as expected.
Although the labels differ, these conditions share important features: pain out of proportion to any visible damage, sensitivity of the nervous system, and a strong impact on sleep, mood and daily function. They also share the same broad management principles, which is why a diagnosis of “chronic pain” is far from a dead end — it points toward a well-established approach that helps most people, even when the pain cannot be eliminated entirely.
How is chronic pain treated?
The most effective approach is multimodal — several treatments working together rather than one single fix. The core elements are graded movement and exercise, education about how pain works, attention to sleep and stress, appropriate use of medication, and psychological support where helpful. Targeted injections have a role for specific pain sources, but rarely solve chronic pain alone.
The table below sets out the main components and what each contributes:
| Approach | What it involves | What it contributes |
| Graded movement | Gradual, planned return to activity and exercise | Rebuilds capacity and confidence; reduces sensitivity |
| Pain education | Understanding how persistent pain works | Reduces fear; changes how the system responds |
| Sleep & stress | Improving sleep quality, managing stress | Poor sleep and stress amplify pain directly |
| Medication | Used selectively and reviewed regularly | Can ease symptoms; rarely sufficient alone |
| Targeted procedures | Image-guided injections for a specific source | Can create a window to progress rehabilitation |
| Psychological support | Strategies for coping and reducing distress | Improves function and quality of life |
Where an injection is used, its value is usually in reducing pain enough to allow rehabilitation to progress — not as a treatment in isolation. Ultrasound guidance ensures it is placed accurately when a specific structure is identified as a pain source.
Why does exercise help when movement is what hurts?
Because graded exercise gradually reduces the nervous system’s sensitivity, rebuilds strength and tolerance, and restores confidence. Started at the right level and progressed slowly, it is one of the most consistently effective treatments for persistent pain — even though it feels counterintuitive.
The key is starting below your current limit and building steadily, rather than testing your pain each session. Small, achievable, regular doses work better than occasional heavy efforts followed by flare-ups. A structured programme, ideally guided initially, helps you find the right starting point and progress without triggering setbacks — and flare-ups, when they happen, are a normal part of the process rather than evidence of failure.
What about opioids and other painkillers?
Medication has a supporting role, not a leading one. Simple analgesics and certain nerve-pain medicines help some people, but strong opioids are generally not recommended for long-term non-cancer pain because their benefits fade while risks including dependence and increased sensitivity to pain grow.
That is not an argument for enduring pain without help — it is an argument for using medication thoughtfully: at the lowest effective dose, reviewed regularly, and always alongside the active parts of treatment rather than instead of them. If medication is not clearly improving your function, that is a reason to review it rather than to increase it.
Frequently asked questions
Does a normal scan mean my pain isn’t real?
Not at all. Pain is generated by the nervous system, and persistent pain can occur without visible tissue damage. A normal scan is useful information — it rules out certain problems and redirects treatment toward what will actually help.
Will I have this pain forever?
Not necessarily. Many people improve substantially, and even where pain persists, function and quality of life can improve a great deal. The goal is progress in what you can do and how you feel, not only a reduction in the pain score.
Should I rest until the pain settles?
Prolonged rest usually makes persistent pain worse by causing deconditioning and increasing sensitivity. Gradual, paced activity is more effective — the skill lies in finding the right starting level and building from there.
Can an injection cure my chronic pain?
Injections can help when a specific structure is identified as a pain source, and they can create a valuable window to progress rehabilitation. They are rarely a cure on their own, and are most effective as part of a broader plan.
Is chronic pain psychological?
Chronic pain is a physical condition involving real changes in the nervous system. Mood, stress and sleep genuinely influence pain — in both directions — which is why addressing them helps, but that does not mean the pain is imagined.
| Living with pain that hasn’t settled?
Persistent pain deserves a thorough assessment — to identify what is genuinely driving it, to explain what your scans do and do not mean, and to build a realistic plan that improves what you can do. Dr Sirisena offers assessment and non-surgical management of long-standing musculoskeletal pain, including image-guided treatment where a specific source is identified.
