When the body remembers: pain and childhood trauma

Some people live with pain that doesn’t fully make sense. Pain that moves. Pain that lingers. Pain that flares without a clear cause. They may have been told:

• “everything looks normal”

• “there’s nothing medically wrong”

• “it might be stress”

And yet, the pain is real.

Very real.

The body doesn’t forget what it had to hold

When we think about childhood trauma, we often think about memories. What happened.What was said. What we can recall. But trauma isn’t only stored as a story.

It’s stored in the body.

In the muscles that learned to tense. In the breath that learned to stay shallow and quiet. In the nervous system that learned to stay alert. The body adapts to survive and sometimes, those adaptations don’t switch off.

What science tells us about pain and trauma

We now know that pain is not just about injury or damage. It’s shaped by the brain and nervous system.

Research shows that early trauma can affect how the brain processes pain, particularly in areas linked to:

• threat detection (like the amygdala)

• emotional processing (such as the anterior cingulate cortex)

• and how the body interprets physical signals

Over time, the nervous system can become more sensitive. This is sometimes called central sensitisation.

It means the body becomes quicker to detect threat, and slower to switch it off. So sensations that might once have felt mild can begin to feel intense, persistent, or overwhelming.

Not because the pain is imagined but because the system processing it has changed.

Pain can serve as a form of protection

This can be hard to hear at first. But some pain is not a sign that something is wrong in the way we think. It can be a sign that something has been held for a long time. If, as a child, you had to:

• stay quiet

• stay small

• stay hyper-aware of others

Then your body may have learned to carry tension as a baseline. Over time, that can show up as:

• chronic muscle pain

• headaches or migraines

• gut discomfort

• fatigue or heaviness in the body

Not because the pain is imagined. But because the body has been working so hard for a long time.

“But that was years ago…”

One of the most common questions is: Why now? I know, because I had that very thought too!

Why, if the trauma is in the past, does the body still react? Well, the nervous system doesn’t work in timelines in the way we might expect. It works in patterns. If something in the present feels similar to the past, even subtly, the body can respond as if it’s happening again. Not consciously. Not deliberately. But automatically.

When pain has no clear medical answer

This is often where people feel most alone. Because when tests come back “normal”, it can feel like:

• not being believed

• not being understood

• or worse, like it’s “all in your head”

But the absence of a clear medical cause does not mean the absence of a real experience.

Pain that is influenced by the nervous system is still pain.

It deserves to be taken seriously.

Your body is not working against you

It can feel that way (I know too well). Especially when pain is unpredictable or persistent.

But your body is not trying to harm you. It is trying to protect you using patterns it learned a long time ago. Even if those patterns are no longer needed in the same way

What helps?

Not forcing the pain away. Not dismissing it. Not pushing through at all costs.

But beginning to understand the body differently.

That might include:

• noticing where you hold tension

• gently reconnecting with your body (at your own pace)

• allowing space for rest, rather than constant endurance

• working with approaches that include the body, not just the mind

For some, this might involve therapies that recognise the link between trauma and the body.

For others, it starts simply with:“this makes sense”.

This is not about blame

Not everything is caused by trauma.

And not all pain can be explained this way.

But for many people, there is a connection that has never been named.

And naming it can bring something important:

Understanding. A different way of relating to the body.

You are not imagining this

If you live with pain that doesn’t fully make sense

If your body feels heavy, tense, or on edge

If you’ve been told “everything is fine” when it doesn’t feel that way

You are not imagining it.

Your body may be carrying something that hasn’t yet had the chance to settle.

And that is something that can be approached with care, with compassion, and over time.

If this resonates, you’re not alone in it.

And your body is not the problem.
