Why Childhood Trauma Can Lead to Chronic Pain

When we think about chronic pain, we often focus on physical causes: injury, illness, genetics. But what if the root cause isn’t just in the body, but also in the mind? More and more research is showing that the effects of childhood trauma don’t just linger in our thoughts or emotions — they can become embedded in our bodies and show up as chronic pain well into adulthood. This may sound surprising at first. How can something that happened decades ago — like neglect, abuse, or a chaotic home environment — contribute to pain in the back, neck, or joints today?

Trauma Changes the Nervous System

When a child grows up in an environment that is unpredictable, frightening, or abusive, their nervous system is constantly on high alert. This is the classic “fight or flight” response. In small doses, this response is useful for dealing with threats. But, when a child is repeatedly exposed to stress without a sense of safety or resolution, the system becomes dysregulated.

Over time, the body essentially forgets how to turn off the alarm bells. The nervous system stays hyperactive and interprets even neutral situations as threatening. This hypervigilance can wear down the body, increase inflammation, and alter how the brain processes pain.

This is why many adults with a history of childhood trauma develop conditions like fibromyalgia, migraines, irritable bowel syndrome (IBS), and chronic fatigue syndrome. These aren’t imagined or exaggerated symptoms. They’re very real, and they often stem from a nervous system that learned to survive in a world that didn’t feel safe.

Trauma and the Immune System

Chronic stress in childhood also disrupts the immune system. A body constantly flooded with stress hormones like cortisol can become chronically inflamed. This inflammation is a key contributor to many types of pain, from arthritis to muscle tension.

Inflammation affects more than just the immune system. It can also interfere with neurotransmitters like serotonin and dopamine, which regulate mood and perception of pain. This helps explain why so many people with chronic pain also struggle with anxiety, depression, and sleep disturbances. It’s all connected: a dysregulated stress response can inflame the body, which alters the brain’s chemistry.

The Brain and Body Remember

Our bodies hold memories of trauma, not necessarily in the form of images or thoughts, but through feelings and reactions. For example, someone who was emotionally neglected as a child may not consciously remember every detail, but they might live with a persistent tightness in their chest, a clenched jaw, or stomach pain that no medical test can explain. These physical symptoms can be the body’s way of expressing pain that the mind hasn’t fully processed. This isn’t to say that every instance of chronic pain is caused by trauma, but for many people, especially those with a history of adverse childhood experiences, they’re linked.

Healing is Possible

Discovering that your chronic pain could be linked to past trauma might feel upsetting, but you also open the door to finally healing. When your pain shifts from not only a physical issue but also an emotional and neurological one, your range of treatment tools expands.

Therapies like EMDR (eye movement desensitization and reprocessing), somatic experiencing, and trauma-informed cognitive behavioral therapy can help regulate the nervous system and reduce the body’s stress load. These approaches won’t only help you process your past; they’ll also teach the body how to feel safe again. Mind-body practices like yoga, breathwork, and meditation can calm the nervous system and build a deeper connection between the mind and body. When the body feels safe, pain often softens.
