Pain is meant to be protective. When you touch a hot surface, twist an ankle, or cut your hand, pain tells you to stop, rest, and pay attention. Usually, as the tissue recovers, the alarm quiets.
But sometimes it does not. Burning, stabbing, electric, tingling, or exquisitely sensitive pain can continue long after an injury appears healed. Clothing may hurt. A light touch may feel sharp. A sensation that began in one small area may seem to spread beyond it.
This does not mean the pain is imagined. It means the nervous system may still be sending danger signals, even when the original injury is no longer the whole story. At The Mood Center, we believe that understanding this distinction matters. It gives people a more accurate language for what they are living with, and a more thoughtful starting point for care.
When pain outlasts the original injury
Neuropathic pain arises from injury or dysfunction involving the nervous system itself. It can follow surgery, shingles, diabetes, trauma, chemotherapy, nerve compression, or other medical conditions. It may also occur alongside an ongoing injury or illness.
The experience is often different from ordinary soreness. People may describe:
Burning, freezing, buzzing, or electric sensations
Pins and needles or numbness
Pain from light touch, pressure, or temperature changes
Pain that seems disproportionate to the original injury
Symptoms that interfere with sleep, movement, concentration, and mood
Not all persistent pain is neuropathic pain. Muscles, joints, inflammation, circulation, and other medical factors can all contribute. A careful evaluation matters, particularly when symptoms are new, worsening, or accompanied by weakness, loss of bladder or bowel control, fever, significant swelling, or other urgent changes.
Conditions such as complex regional pain syndrome illustrate how profoundly pain processing can change after an injury. In this condition, pain may persist with sensory, motor, autonomic, and skin changes that extend beyond a simple tissue-healing timeline. Research on complex regional pain syndrome describes the evolving understanding of these overlapping nervous-system mechanisms (Limerick et al., 2023).
Central sensitization: when the alarm becomes too responsive
Central sensitization refers to increased responsiveness within the central nervous system, meaning the brain and spinal cord become more reactive to incoming signals. The alarm has not simply stayed on. In some cases, it has become easier to trigger and harder to turn down.
This can help explain why a light touch can hurt, why pain can linger after an injury heals, or why stress, poor sleep, and repeated flares may make symptoms feel more intense. The nervous system is adaptable. That adaptability is useful when it helps us learn and protect ourselves. It becomes burdensome when pain pathways remain organized around threat.
Central sensitization is not a character flaw, and it is not evidence that you are exaggerating. It is also not a diagnosis that should be applied casually to every difficult pain problem. We look at the full clinical picture, including your medical history, prior injuries, medications, symptoms, functional goals, and any care you have already tried.
Tissue healing and pain signaling are not always on the same clock
A healed fracture, incision, or strained muscle can be reassuring news. Yet imaging and physical healing do not always capture what is happening in the pain pathways. The nerves that carry sensation, the spinal cord that filters it, and the brain that interprets it all remain involved.
That is why persistent pain deserves more than a quick dismissal. It may require attention to the original cause, but also to sleep, mobility, stress physiology, medication effects, mood, and the patterns that keep the nervous system on alert.
We try to make room for both truths at once: pain can be biologically real and deeply disruptive, and a scan or exam may not fully explain its intensity. Neither truth cancels the other.
Why ketamine enters the conversation
Ketamine is a medication that has been used in medical anesthesia for decades. In pain care, its action at the NMDA receptor has drawn attention because NMDA signaling is involved in processes related to pain amplification and sensitization. A clinical review of ketamine and chronic neuropathic pain notes that its pharmacology, dosing, and patient selection require careful consideration rather than a one-size-fits-all approach (Kamp et al., 2019).
We offer ketamine for chronic and neuropathic pain as an individualized clinical option. Ketamine use for neuropathic pain is off-label, meaning the FDA has not approved ketamine specifically for this purpose. Off-label prescribing can be medically appropriate when a clinician determines that the potential benefits, risks, alternatives, and monitoring needs fit a particular patient.
The evidence is still developing, and outcomes vary. Reviews of ketamine in chronic and cancer-related pain emphasize both its potential role in selected cases and the need for individualized protocols, monitoring, and attention to adverse effects. Evidence on ketamine in chronic pain management reflects that balance (Culp et al., 2020).
For some people, an IV ketamine therapy consultation may be part of a broader discussion. For others, an IM ketamine injection format may be considered. The appropriate route, if ketamine is appropriate at all, depends on your health history, symptoms, medications, and clinical goals.
What we emphasize before beginning care
Persistent pain often creates understandable urgency. When daily life has narrowed around symptoms, people may want a clear answer immediately. We do not minimize that urgency, but we also do not treat it as a reason to rush past the details.
Before considering ketamine, we want to understand the pattern of your pain and the care surrounding it. This includes medical diagnoses, current medications, substance-use history, blood pressure and cardiovascular considerations, psychiatric history, and the practical realities of treatment and follow-up.
We also encourage continued coordination with the clinicians involved in your overall care. Ketamine is not a substitute for evaluating new neurologic symptoms, treating an underlying medical condition, or maintaining appropriate rehabilitation and pain-management supports.
A small human study found that changes in temporal pain summation and certain brain measures were associated with response patterns following ketamine. It is an important area of investigation, but it does not create a simple test that can predict who will benefit. Research on neuropathic pain response patterns underscores both the promise and the complexity of this work (Mills et al., 2024).
Two questions we hear often
“If my injury healed, why does it still hurt?”
Because tissue recovery and nervous-system recovery can proceed at different speeds. Persistent signaling may reflect nerve injury, increased sensitivity in pain pathways, ongoing inflammation, movement changes, sleep disruption, or a combination of factors. An evaluation can help clarify what deserves attention now.
“Does ketamine work for everyone with nerve pain?”
No. Neuropathic pain has many causes, and individual responses differ. Clinical experts continue to debate how ketamine should be used in chronic pain, including questions of patient selection, treatment setting, dosing, and outcome measurement. A Delphi survey of chronic pain clinicians reflects the need for careful, case-by-case decision-making (Voute et al., 2022).
If you are considering this option, our ketamine FAQs can help you begin with practical questions. We can then discuss whether an evaluation at our Annapolis or Columbia office makes sense for you.
Key takeaways
Central sensitization can make pain feel louder, wider, and more persistent than the original injury alone would suggest. It is a nervous-system process, not a failure of willpower.
Neuropathic pain deserves a careful medical assessment. Not every persistent symptom has the same cause, and not every person needs the same kind of care.
At The Mood Center, we approach ketamine for neuropathic pain with attention to the whole person, the medical context, and the limits as well as the possibilities of treatment. If you are living with persistent burning, tingling, electric, or hypersensitive pain, we invite you to reach out and schedule a consultation.
