Chronic pain often doesn’t follow the rules.
The scans look normal. The surgery was technically successful. Yet the pain continues.
Because sometimes the problem isn’t the hardware.
Sometimes it’s the software.
The nervous system is not a passive wire carrying pain signals to the brain. It’s an active protection system. A prediction engine. And like any protection system, it can become overprotective.
The volume dial gets stuck on high.
A harmless touch burns. A simple movement feels dangerous. Pain spreads beyond the original injury. Stress, trauma, poor sleep, and fear begin shaping the experience more than tissue damage itself.
This is what modern pain science calls central sensitisation.
The system learns pain.
And once the software changes, hardware-only solutions often disappoint.
Another scan.
Another surgery.
New hardware. Same error message.
This changes everything about treatment.
Because software pain needs software treatments.
That starts with retraining the nervous system:
- Pain neuroscience education
- Graded movement
- Stress regulation
- Sleep optimisation
But for many patients with severe or persistent central sensitisation, modern pain medicine is increasingly turning toward therapies designed to directly reset the operating system itself.
Ketamine Infusions: Rebooting the Pain System
Ketamine is no longer just an anaesthetic.
In chronic pain medicine, it has emerged as one of the most important treatments for software-driven pain.
Why?
Because ketamine targets the very circuitry responsible for central sensitisation.
When pain persists for months or years, the nervous system becomes trapped in amplified signalling loops. NMDA receptors in the brain and spinal cord become overactive. The system becomes hypersensitive. Protective becomes pathological.
Ketamine interrupts that loop.
It blocks NMDA receptors, reducing the “wind-up” effect that keeps the nervous system stuck in chronic pain mode. But its effects go further:
- Reducing central sensitisation
- Dampening neuroinflammation
- Modulating trauma and mood circuitry
- Creating a window for the nervous system to recalibrate
This is why ketamine infusions can be transformative in conditions like:
- CRPS
- Fibromyalgia
- Neuropathic pain
- Chronic migraine
- Persistent spinal pain
- Trauma-associated chronic pain
Not because it masks pain.
Because it changes how the system processes pain.
For some patients, ketamine becomes the first treatment that addresses the actual driver of their symptoms rather than chasing tissues that already healed long ago.
Stellate Ganglion Block: Turning Down Fight-or-Flight
There’s another piece of the software system many people miss:
The autonomic nervous system.
The body’s fight-or-flight circuitry.
For some chronic pain patients, especially those with CRPS, trauma histories, PTSD, anxiety, or persistent stress activation, the sympathetic nervous system becomes locked in overdrive.
Always scanning.
Always guarding.
Always amplifying danger.
The stellate ganglion is part of this sympathetic network.
A Stellate Ganglion Block (SGB) works by temporarily interrupting that overactive signalling pathway.
And sometimes, when the fight-or-flight loop quiets down, the pain system quiets down too.
Patients often describe:
- Reduced pain intensity
- Less burning and sensitivity
- Improved sleep
- Feeling calmer or “lighter”
- A nervous system that finally feels safe again
SGB is increasingly being used in:
- CRPS
- PTSD-associated chronic pain
- Sympathetically maintained pain
- Chronic headaches
- Trauma-linked central sensitisation
Not as a miracle cure.
As a reset.
A chance for the nervous system to stop sounding the alarm long enough for rehabilitation and recovery to finally gain traction.
The Future of Pain Medicine
Ketamine infusions and Stellate Ganglion Blocks are not competing therapies.
They target different parts of the software system:
- Ketamine calms the amplified pain-processing circuitry
- SGB downregulates the fight-or-flight network
For many patients, especially those with complex chronic pain, trauma, CRPS, or severe sensitisation, combining both within a multidisciplinary programme can be extraordinarily powerful.
Because chronic pain is rarely just structural.
It is neurological.
Physiological.
Emotional.
Protective.
Learned.
And treatable.
This is the part many patients need to hear:
If your scans are normal, your pain is not imaginary.
The software is real.
And software can be updated.
