Ketamine clinics are increasingly common, and many patients now hear about ketamine as a potential treatment for chronic pain. Online, it is sometimes described as a miracle cure.
The reality is more nuanced. Ketamine can be a powerful tool for the right patient, but it is not a solution for every type of pain.
What Ketamine Can Help With
Ketamine works on the nervous system, particularly through NMDA receptor activity, which is involved in pain amplification and central sensitization.
In chronic pain, the nervous system can become hyper-reactive. Pain signals may become amplified, and the body may remain stuck in a protective, fight-or-flight state long after the original injury or trigger began.
Ketamine may help quiet this overactive signaling. It is often most relevant in conditions involving central sensitization, neuropathic pain, and Complex Regional Pain Syndrome.
For some patients, ketamine may also create a temporary window of emotional and nervous system distance from pain. This can be meaningful when chronic pain is associated with medical trauma, fear, hypervigilance, or severe distress.
What Ketamine Does Not Do
Ketamine does not repair a torn labrum, stabilize a hypermobile joint, reverse a herniated disc, or treat an active autoimmune flare.
If pain is being driven by a focal mechanical problem, ketamine may reduce the intensity of the pain experience, but it does not fix the structure causing the signal. The underlying driver still needs to be identified.
Ketamine also should not be treated as a daily escape from pain. Used too frequently or without a broader plan, it can lose effectiveness and may create psychological dependence, tolerance, or other risks.
Why the Workup Still Matters
The key question is not simply, “Will ketamine help?”
The better question is: What kind of pain is this?
Is the pain neuropathic? Is the nervous system sensitized? Is there CRPS? Is there mechanical instability, inflammatory disease, migraine, autoimmune activity, or pelvic or spine pathology that needs to be addressed directly?
Ketamine may help turn down the volume of a sensitized nervous system, but that window of calm should be used to investigate what is driving the pain.
Our Approach at MPM
At Manhattan Pain Medicine, we use ketamine as one tool within a broader diagnostic and treatment plan, helping patients understand whether their pain is primarily nervous-system driven, mechanical, inflammatory, or layered.
