For many people living with chronic pain, the most confusing part isn’t the discomfort itself—it’s the lack of clear answers. Imaging looks normal. Surgeries are complete. Physical therapy has been exhausted. Medications barely touch the pain, if they help at all. Yet the pain remains, sometimes worsening over time.

This is often the reality for patients with central sensitization, a condition in which the nervous system becomes stuck in a state of high alert. The pain is real, but it no longer reflects ongoing tissue damage. Instead, the brain and spinal cord have learned pain—and they keep repeating it.

This process is commonly referred to as the “wind-up phenomenon.” Once it begins, traditional pain treatments often act like band-aids: they may dull symptoms temporarily but fail to address the underlying neurological loop driving the pain.

At New Hope Infusion, we focus on treatments that work at the source of this cycle. Ketamine infusion therapy offers a unique way to interrupt central sensitization, calm overactive pain circuits, and give the nervous system a chance to reset.

Defining Central Sensitization: Why Pain Becomes Self-Sustaining

Central sensitization occurs when the central nervous system—specifically the spinal cord and brain—becomes hypersensitive to stimuli. In this state, the nervous system amplifies pain signals even in the absence of ongoing injury.

Conditions Commonly Associated with Central Sensitization

• Fibromyalgia

• Complex Regional Pain Syndrome (CRPS)

• Failed Back Surgery Syndrome

• Chronic migraine

• Chronic pelvic pain

• Neuropathic pain syndromes
  

Patients may experience:

• Pain spreading beyond the original injury site

• Pain triggered by light touch or movement

• Heightened sensitivity to temperature, sound, or stress
  

Why Standard Painkillers Often Fail

Most traditional pain medications target peripheral pain—pain caused by inflammation or tissue damage. Examples include:

• NSAIDs (ibuprofen, naproxen)

• Opioids

• Steroid injections

However, in central sensitization, the problem is not the tissue—it’s the signal processing system itself. The spinal cord neurons become increasingly responsive, firing repeatedly in response to minimal input. This escalation is known as wind-up.

Because opioids and NSAIDs do not correct this neural overactivity, patients often experience diminishing returns or worsening symptoms over time.

The Science of the Reset: How Ketamine Stops the Wind-Up Cycle

Ketamine infusion therapy addresses chronic pain in a fundamentally different way.

The Role of the NMDA Receptor

At the center of wind-up and central sensitization is the NMDA (N-methyl-D-aspartate) receptor, a critical receptor in the glutamate system. When overactivated:

• Pain signals become exaggerated

• Neurons fire repeatedly without adequate inhibition

• Pain becomes persistent and self-reinforcing

Ketamine is a potent NMDA receptor antagonist, meaning it temporarily blocks this pathway.

Interrupting Chronic Nerve Firing

By inhibiting NMDA receptor activity, ketamine:

• Reduces excessive excitatory signaling

• Interrupts spinal cord wind-up

• Calms hyperactive pain networks

This allows the nervous system to shift out of constant alarm mode.

Neuroplasticity and Long-Term Relief

Ketamine also promotes adaptive neuroplasticity, helping the brain rewire unhealthy pain pathways. Research shows ketamine increases:

• Brain-Derived Neurotrophic Factor (BDNF)

• Synaptic connectivity in pain-modulating regions

Rather than masking pain, ketamine helps retrain the nervous system, which is why some patients experience sustained relief even after the infusion series ends.

This mechanism makes ketamine particularly effective for patients whose pain has not responded to conventional therapies.

Initial Evaluation

At New Hope Infusion, treatment begins with a comprehensive medical assessment to determine:

• Pain history and diagnosis

• Prior treatment response

• Mental health considerations
  

The Infusion Experience

During a ketamine infusion:

• The medication is administered intravenously

• Vital signs are continuously monitored

• Patients typically relax in a calm, controlled environment

Infusions generally last 40–60 minutes. Patients may experience mild dissociation, relaxation, or altered perception, which resolves shortly after the session.

Series-Based Treatment

For chronic pain, ketamine is often administered as a series of infusions, allowing cumulative effects on pain pathways. Treatment plans are individualized based on response and tolerance.

Patients usually require a ride home after each session and can resume normal activities the following day.

Frequently Asked Questions

Is ketamine only for severe pain conditions?
Ketamine is most effective for chronic, treatment-resistant pain, particularly when central sensitization is involved.

Will ketamine cure my pain?
Ketamine is not a cure, but it can significantly reduce pain intensity and improve function by addressing the underlying neural mechanisms.

How soon will I feel relief?
Some patients notice improvement after the first infusion, while others experience gradual relief over the course of treatment.

Is long-term use safe?
When administered intermittently in a medical setting, ketamine has a strong safety record.

Central sensitization transforms pain into a neurological loop that traditional treatments often cannot break. Ketamine infusion therapy offers a way forward—by targeting the NMDA receptors that drive wind-up and restoring balance to the nervous system.

If you are searching for a ketamine clinic near me that understands complex chronic pain, New Hope Infusion provides medically supervised, evidence-based care designed to address pain at its source. Schedule a consultation and take the next step beyond temporary relief.

Chronic pain is not just physically exhausting—it is mentally overwhelming. Many patients describe it as a constant background “noise” that never shuts off.

Pain and Anxiety Are Intertwined

Persistent pain activates the brain’s threat and fear centers, particularly the amygdala. Over time, this leads to:

• Heightened anxiety

• Hypervigilance

• Pain-related catastrophizing (“This will never get better”)

These emotional responses further amplify pain perception.

Why Ketamine Helps Both Mind and Body

Ketamine’s effects extend beyond pain modulation. By calming overactive limbic circuits, ketamine can:

• Reduce anxiety and emotional distress

• Improve mood and mental clarity

• Decrease fear associated with movement or flare-ups

Many patients report feeling a sense of mental quiet for the first time in years. This psychological relief is not incidental—it plays a crucial role in long-term pain recovery.

When the brain is no longer overwhelmed, patients can re-engage with therapies and daily activities that support healing.
