Pain isn’t actually created in your tissues. When you injure yourself, specialised nerve endings detect changes that could be potentially threatening — things like pressure, heat, chemical changes, or tissue irritation. They send information through the nervous system towards your brain.

But that information isn’t pain. 

Your brain creates the experience of pain. The brain (the alarm) receives information from your body (the source of the smoke) and then has to interpret it. The brain needs to decide if the alarm should go off or not. It is constantly asking, largely outside of your conscious awareness: “How much of a threat is this?”

The answer isn’t based solely on what is happening to your tissues. It considers it alongside everything else it knows about you and the situation:

• Your previous experiences with pain and injury

• Your beliefs about damage or harm

• How safe you feel in your current environment

• What is happening around you and where your attention is focused

• Your current emotional state

All of this information can influence how much pain you experience. Sometimes the alarm is accurate and appropriate and there is real danger. Sometimes it can be too sensitive and the alarm may go off even when you are safe.

Imagine walking down a dark alley at night. You hear footsteps behind you. You immediately feel a change in your body: your heart rate increases, your muscles tense, and your attention sharpens on the threat. You haven’t consciously decided to do any of this. Your brain detected danger and activated your protective system. Pain works in the exact same way — when danger is perceived, your nervous system dials up sensitivity to keep you safe.

Your brain is constantly assessing information from your body and deciding how much protection might be necessary.

The same injury doesn’t always mean the same pain

Imagine two people break their ankle in very similar circumstances.

Both have tissue damage. Both have information travelling from the injured ankle towards the brain. Yet their experiences of pain can be completely different.

But they may experience very different amounts of pain. One person might think:

“Thank goodness I know what this is. It will heal and I’ll be back on my feet.”

Another might think:

“I’ve really damaged it. What if something is seriously wrong? What if I can’t walk properly again?” 

The physical injury may be identical, but the experience of pain will likely not be. This doesn’t mean that one person’s pain is real and the other’s isn’t. It doesn’t mean pain is “all in your head.” Both people are experiencing real, valid pain. It simply means that pain is not a direct measurement of tissue damage.

What Does This Mean for You? 

This is one of the most important principles in modern pain science:

Pain is real, but pain and damage are not the same thing. Your tissues provide information. Your nervous system carries that information. Your brain interprets it within the context of everything else it knows. The resulting experience is pain. 

This is why two people can have very similar injuries and completely different pain experiences. It is also why you can sometimes continue to experience pain even after an injury has physically healed.

Understanding this doesn’t make your pain any less real. Instead, it gives us a different way of thinking about it. Rather than simply asking “What is damaged?” we can also start asking “Why does my brain think I need protecting?” 

And that simple shift in perspective can fundamentally change the way we approach persistent pain and recovery.
