DEEP DIVE · CHAPTER 26
The Pain-Dopamine Loop
Chronic pain and low dopamine drive each other in a loop: persistent pain dampens the dopamine system, and a dampened system amplifies pain. The Chapter 26 Deep Dive gives the brain scans, the drug results and the sleep disorder almost nobody screens for.
If you have ever been told your pain is in your head, this is the chapter I wrote for you. Long pain turns the dopamine system down, and a turned-down dopamine system makes the pain louder — and both halves of that have been measured in living people. I will show you what the scans found, what the drugs did and did not do, the sleep disorder almost nobody screens for, and the one word in pain medicine that has done more harm than most drugs.

The book makes the argument. This Deep Dive shows the evidence, claim by claim: the study, who was in it, the number and where it sits in the paper, what it does not show — and the questions to bring to your own physician. It is written to be shared with your doctor.

Frequently asked questions
Does chronic pain lower dopamine?
Yes. Long-lasting pain turns the dopamine system down, and that change has been measured in living people. It is one half of a loop: persistent pain dampens the dopamine system, and a dampened system amplifies pain. The Chapter 26 Deep Dive gives the brain scans behind it, with 20 verified references, written so you can hand it to your physician.
Does low dopamine make pain worse?
Yes. A turned-down dopamine system makes pain louder. That is the second half of the loop in Chapter 26: pain lowers dopamine, and low dopamine raises pain, and each keeps the other going. Both halves have been measured in living people. The Deep Dive shows what the scans found and what the drugs did and did not do.
Is chronic pain all in your head?
No. If you have ever been told your pain is in your head, Dr. Padda wrote Chapter 26 for you. The brain is part of the mechanism, but that makes the pain biological, not imagined: persistent pain dampens the dopamine system, and a dampened system amplifies pain. The Deep Dive also covers a sleep disorder almost nobody screens for.
