Understanding nociplastic pain

You have been told that some or all of your pain is nociplastic. It means your nervous system has become amplified. The alarm system that detects and reports pain has turned its volume up and left it there. The pain you feel is genuine. What has changed is not the tissue; it is how your spinal cord and brain process the signals coming from it.

The most important point

The three types of pain

These categories are not mutually exclusive. Most of our patients have a mixed pain picture. You can have a real disc herniation, real arthritis, or a real prior surgery and have a nociplastic component layered on top. Recognizing that layer is what allows us to stop chasing the wrong target. Read more about the three types of pain.

What is physically happening

Several measurable changes occur in the nervous system in nociplastic pain. These are not theoretical. They have been demonstrated in laboratory testing, functional brain imaging, and spinal fluid studies.

1. 1

   Central sensitization

   Pain-carrying nerve cells in the spinal cord become hyperexcitable. Receptors on these cells, particularly NMDA receptors, are switched on and stay on, so a signal that should produce a small response instead produces a large one. Over time these connections physically strengthen, the same way a memory is consolidated. Your spinal cord has, in effect, learned the pain.

2. 2

   Loss of the body's built-in pain brakes

   Your brainstem normally sends signals down the spinal cord that suppress incoming pain traffic. This is why a soldier can be injured and not feel it until later. In nociplastic pain, this descending inhibitory system underperforms and the descending facilitating system dominates. Less brake, more accelerator. This is measurable in the laboratory and is one of the most reproducible findings in this condition.

3. 3

   Neuroinflammation and glial activation

   Glial cells, the support cells of the nervous system, shift into an activated, inflammatory state and release chemical messengers that keep neighboring pain neurons excitable. This is inflammation inside the nervous system, not in your joints or muscles, which is why anti-inflammatory pills do so little for it.

4. 4

   Altered brain chemistry and connectivity

   Imaging studies in people with nociplastic pain consistently show elevated glutamate, the main excitatory chemical, and reduced GABA, the main calming chemical, in pain-processing regions, along with altered communication between the insula, the anterior cingulate cortex, and the brain's resting network. This is the biological reason the pain feels constant and intrusive even at rest.

5. 5

   Amplifiers

   Poor sleep, physical deconditioning, sustained stress, and untreated mood disorders all measurably lower pain thresholds and sustain the changes above. This is also why treating them is not a consolation prize. It is direct treatment of the mechanism.

Symptoms you may recognize

• Widespread or shifting pain. Multiple body regions, or pain that moves and does not respect a single nerve or joint pattern.
• Pain out of proportion to the findings on imaging or examination.
• Allodynia. Ordinary touch hurts: bedsheets, waistbands, a bra strap, a light hug.
• Hyperalgesia. Painful things hurt far more and far longer than expected, including after minor procedures.
• Sensory sensitivity beyond pain. To bright light, loud sound, strong odors, cold, or heat.
• Non-restorative sleep. You sleep hours but wake unrefreshed and stiff.
• Fatigue that is not proportional to activity.
• Cognitive symptoms. Word-finding difficulty, poor concentration, short-term memory lapses.
• Flares triggered by weather change, stress, overexertion, illness, or poor sleep.

Commonly associated conditions include irritable bowel syndrome, interstitial cystitis or bladder pain syndrome, jaw pain, tension and migraine headache, restless legs, and pelvic pain. When several of these cluster in one person, it points strongly to a nociplastic mechanism.

How it is diagnosed

There is no blood test and no scan for nociplastic pain. It is a clinical diagnosis, made by pattern recognition: the distribution and quality of your pain, your examination, your associated symptoms, your response to prior treatments, and the absence of a structural finding that adequately explains the picture. Validated questionnaires may be used to quantify how widespread your pain is and how severe the associated symptoms are.

Importantly, we still evaluate for other causes. Thyroid disease, inflammatory arthritis, vitamin D deficiency, sleep apnea, and anemia can all mimic or worsen this picture and are worth ruling out.

What works, and what does not

Medications with the best evidence

• Duloxetine and milnacipran (SNRIs). FDA-approved for fibromyalgia. They restore the descending inhibitory pathways described above.
• Pregabalin and gabapentin. Pregabalin is FDA-approved for fibromyalgia. Both reduce excitatory neurotransmitter release.
• Low-dose tricyclics at bedtime. Amitriptyline or nortriptyline, and low-dose cyclobenzaprine. Doses used for pain are far below antidepressant doses; they improve both pain and sleep quality.
• Low-dose naltrexone. An off-label option targeting glial activation, with promising early trial evidence and a favorable safety profile.

Expect to trial more than one agent. Response is individual, benefit builds over weeks, and combination therapy at modest doses often outperforms a single drug pushed to maximum.

Useful adjuncts

• Aquatic therapy, yoga, and mindfulness-based stress reduction
• Correcting vitamin D deficiency; weight management where relevant
• Treating the coexisting conditions: migraine, irritable bowel, jaw pain, sleep apnea

Where procedures fit in

We are an interventional practice, and interventional treatment still has a place, but the target matters. Injections, nerve blocks, radiofrequency ablation, and neurostimulation treat nociceptive and neuropathic generators. When you have a genuine facet-mediated pain, a specific inflamed nerve root, or a discrete peripheral nerve problem, treating it is worthwhile, and reducing that ongoing input can help settle the amplification.

What a procedure cannot do is reverse central sensitization on its own. If we recommend an injection, we will tell you specifically which pain generator we are targeting and what portion of your pain we expect it to address. If your relief is partial or short-lived, that is often expected and informative: not a failure, and not a reason to escalate to a bigger procedure.

Setting realistic expectations

Be direct with us and we will be direct with you. Nociplastic pain is usually managed rather than cured. The realistic and achievable goal is meaningful reduction in pain intensity and flare frequency, with substantial gains in sleep, function, and independence.

Progress is measured in months, not visits, and it is rarely linear. Expect good stretches interrupted by flares. Patients who do best are the ones who work several levers at once: consistent movement, protected sleep, an appropriate medication regimen, and active engagement with the therapy side. Any one of these alone underperforms.
