Ketamine for Neuropathic Pain

Neuropathic pain is closely linked to a process known as central sensitization. Over time, damaged nerves can cause the central nervous system to become overly reactive, amplifying pain signals or generating them without any trigger at all. This creates a feedback loop where even minor stimulation—like touch, pressure, or temperature—feels severely painful. Ketamine interrupts this loop at its source.

As an NMDA receptor antagonist, ketamine inhibits excessive glutamate signaling in the brain and spinal cord. This action helps calm hyperactive neurons, decrease excitability in pain-processing centers, and reset dysfunctional synaptic patterns. In clinical terms, ketamine promotes “neuroplasticity”—the brain’s ability to reorganize and repair itself—which is essential for reducing pain perception long-term.

Importantly, ketamine’s mechanism differs from standard nerve pain medications like gabapentin or opioids. While those options focus on dampening symptoms, ketamine addresses the underlying neurotransmitter imbalances. Patients at NY Ketamine Infusions frequently report that their pain becomes less constant, less severe, and less intrusive after completing an infusion series. Many also experience better sleep, fewer pain flares, and an increased ability to perform tasks that were once intolerable—from walking and sitting to working and socializing.
