PTSD and Chronic Pain: Why They So Often Go Together

Many people living with chronic pain also carry the weight of trauma. And many people with PTSD experience physical pain that doctors struggle to explain. This is not a coincidence.

Understanding why these two conditions are so deeply connected is the first step toward treating both.

The Nervous System Is the Common Thread

PTSD and chronic pain both involve the nervous system becoming stuck in a state of high alert. After trauma, the brain learns to anticipate danger. It amplifies threat signals and struggles to return to a resting state.

This same process affects how the body perceives pain. In a condition called central sensitization, the nervous system becomes hypersensitive to stimuli. Signals that would not normally register as painful are interpreted as threatening. Pain that should subside after an injury continues long after healing.

People with PTSD are at higher risk for central sensitization because trauma literally rewires how the brain and spinal cord process incoming signals. Learn more about central sensitization syndrome and how it contributes to persistent pain.

The Relationship Works Both Ways

Trauma can cause or worsen chronic pain. But chronic pain can also trigger or intensify PTSD symptoms.

Ongoing physical pain is itself a stressor. It disrupts sleep, limits activity, isolates people socially, and produces a constant undercurrent of suffering. For someone already vulnerable to trauma responses, this level of chronic stress can activate or deepen PTSD symptoms.

Medical trauma is another important factor. Serious injuries, surgeries, ICU stays, or frightening diagnoses can all cause PTSD. When the trauma is physically embodied in the body itself, such as through an injury, the pain can become a constant reminder of the traumatic event. This reinforces the trauma response and keeps the nervous system activated.

How PTSD Shows Up in the Body

PTSD is often thought of as a psychological condition. But its effects on the body are very real and measurable.

Hypervigilance, one of the hallmark symptoms of PTSD, keeps muscles in a near-constant state of tension. This contributes to chronic musculoskeletal pain, headaches, and jaw pain. Sleep disturbances common in PTSD prevent the body from recovering and lower pain tolerance. The stress hormones chronically elevated in PTSD, particularly cortisol, contribute to inflammation throughout the body.

People with PTSD are more likely to develop conditions including fibromyalgia, chronic migraines, irritable bowel syndrome, and chronic back and neck pain. These are not imaginary symptoms. They are the body's measurable response to a nervous system under sustained stress.

Why Treating One Condition Can Help the Other

Because PTSD and chronic pain share underlying mechanisms, interventions that address the nervous system can benefit both conditions at the same time. This is central to the approach at Mind + Body Medicine.

Ketamine Infusion Therapy

Ketamine works on NMDA receptors in the brain, which play a key role in both pain processing and mood regulation. By interrupting overactive pain pathways, ketamine infusion therapy can reduce the hypersensitivity that drives chronic pain while also promoting neural plasticity. Patients often report rapid improvement in PTSD symptoms following a series of infusions.

Ketamine-Assisted Psychotherapy

For patients dealing with trauma alongside chronic pain, ketamine-assisted psychotherapy combines the neurological effects of ketamine with guided therapeutic work. The ketamine creates a window of increased neuroplasticity, during which patients may be more able to process and reframe traumatic memories. This approach targets both the psychological and physical dimensions of the PTSD-pain cycle.

Brain Stimulation (TMS)

Transcranial magnetic stimulation, or TMS, uses electromagnetic fields to stimulate targeted areas of the brain. Brain stimulation therapy can help regulate the areas of the brain responsible for mood and threat response. It has shown benefit in both PTSD and chronic pain conditions by helping the brain reset patterns of overactivation.

Stellate Ganglion Block

The stellate ganglion is a bundle of nerves in the neck that plays a role in the body's stress response. A stellate ganglion block (SGB) is an injection of local anesthetic that temporarily interrupts signaling through these nerves. This can help reset an overactive sympathetic nervous system. Many patients report reduced hypervigilance, anxiety, and reactivity within hours or days of the procedure. For patients whose pain is maintained by sympathetic nervous system activity, SGB may also provide pain relief.

Brain Mapping

Before treating complex cases, Dr. Cohen often uses quantitative EEG brain mapping to identify specific patterns of brain activity. This helps guide treatment decisions for patients dealing with both PTSD and chronic pain, ensuring a personalized approach rather than a one-size-fits-all protocol.

A Mind and Body Approach Is Not Optional. It Is Necessary.

When PTSD and chronic pain are treated in isolation, results are often incomplete. A patient may make progress with a pain specialist but continue to suffer because the underlying trauma response is never addressed. Conversely, a patient working with a mental health provider may improve emotionally but continue to experience pain that was never properly treated.

At Mind + Body Medicine, Dr. Howard Cohen treats the nervous system as a whole. His background spans pain medicine, psychiatry, and psychosomatic medicine, which allows him to address the full picture of how trauma and pain interact.

If you or someone you know has been living with both PTSD and chronic pain, effective treatment is available. Contact Mind + Body Medicine in Dallas to schedule a consultation.
