The Mind-Pain Connection

All Pain Is Produced by the Brain

This might sound surprising, but every pain experience is generated by the brain.

This does not mean pain is fake. When something is wrong in your body, signals travel to the brain, and the brain creates the experience of pain. In other words, the brain is the "factory" where pain is made.

Sometimes the Brain Turns Up the Volume

Think of a TV remote control. Pain signals are like the volume on your TV.

• Acute pain (such as a new injury): the volume matches the actual tissue damage
• Chronic pain (lasting 3 months or more): the brain can turn the volume dial up on its own

This "turned-up volume" state is called central sensitization. The International Association for the Study of Pain (IASP) has formally recognized this as a distinct pain category called "nociplastic pain" — meaning pain that arises from altered pain processing in the nervous system, rather than from ongoing tissue damage or nerve injury.

When central sensitization occurs:

• Normally painless stimuli (like a light touch) can trigger pain
• Minor discomfort gets amplified into significant pain
• Pain persists long after tissues have healed

This is not imaginary. It is a measurable change in the brain and spinal cord's nervous system.

Research has shown that poor sleep, stress, anxiety, and depression can worsen this sensitization.
