What is The Pained Brain about?

The Pained Brain: Chronic Pain: Felt in the Body, Made in the Brain is the second book in The Brain series, written by Dr. Gurpreet Singh Padda, MD, MBA, MHP, with Dr. KrisJay Fucanan, MD. Nectar Media Group published it on September 16, 2026 (ISBN 978-0-9832058-1-4), in paperback and Kindle on Amazon.

Chronic pain gets treated as a worn joint and a bad scan. Most of it is a body running on high insulin, in a fire that never finished. That is why the pain outlives every procedure aimed at the joint.

The book asks three questions. Why does a sore shoulder predict a metabolic death? Why does the scan that looks so convincing explain almost nothing? What does it mean to treat the terrain instead of the joint?

What does chronic pain really cost?

Ask and you get a dollar figure. The CDC puts it at 722.8 billion dollars a year. That is the bill.

The cost is paid in years. Between 1999 and 2023, 67,417 American death certificates named chronic pain as a contributing cause, and the rate rose nearly tenfold.

The terrain underneath is getting worse. Insulin resistance among nondiabetic adults rose from 24.8 to 38.4 percent between 1999 and 2018. Meanwhile, degenerative findings on a scan are common in people with no pain at all. A population growing steadily more insulin resistant, imaged by machines that find something on nearly everyone: that is how a system ends up treating pictures instead of people.

What does "treat the terrain" mean for pain?

It means following the same four pillars as The Starved Brain, fuel, structure, nutrients and inflammation, into the nervous system.

• Fuel. Insulin held high to keep blood sugar normal closes the vessels inside a nerve and turns up the pain alarm for twenty years before any sugar test turns positive.
• Structure. Glucose bonds permanently to the collagen in tendons, discs and nerve tunnels. Tissue turns to glass.
• Nutrients. The shortfalls that decide whether a repair holds.
• Inflammation. The molecules that make an inflamed joint throb are built inside your body from the fat you swallowed.

What are the twenty-two chapters?

1. The Cost of Pain: Mortality and Metabolic Collapse. Pain is paid in years.
2. The Signal versus The Diagnosis. Pain is a signal. Trace it before you silence it: which structure, which mechanism, which terrain.
3. The Illusion of the Scan. Your MRI is lying. What scans find in people who feel fine, and why placebo operations matched the real ones.
4. Chronic Hyperinsulinemia. Insulin is starving your nerves.
5. The Dietary Chemical Factory. The oil in the pan. From omega-6 seed oils to three randomized trials that cut headache days by changing the plate.
6. Advanced Glycation End Products. Why trigger finger, carpal tunnel and frozen shoulder show up years before anyone says diabetes.
7. The Broken Master Clock. Your painkillers are offline. Pain peaks at three in the morning because your own pain control runs on a clock, and one bad night lowers the threshold measurably.
8. The Stress Rewire. "Just stress?" Half right. Stress changes cortisol, immune cells, the cortex and the pain threshold. "Just stress" is a dismissal, not a diagnosis.
9. Central Sensitization. The knob is not the knee. A nervous system turned into a biological amplifier. It can be seen, measured, predicted and turned back down.
10. The Emergency Room Mismatch. Not dying is not a diagnosis. Three in a hundred back-pain patients need the emergency room; ninety-seven are in the wrong one, and a great many long-term opioid prescriptions begin there.
11. The Cluster Headache Emergency. Minutes, not weeks. The attack ends in forty-five minutes, the treatments that work act in fifteen, and the correct diagnosis takes a median of eleven years.
12. Misaligned Incentives in Healthcare. The needle became the plan. Pay formulas reward volume, which is how a patient reaches a ninth epidural. The money also arrives as lunch.
13. Procedural Precision. Aiming is not seeing. A blind injection often lands off target. Dr. Padda does every procedure under live imaging with an awake patient, because a steroid can hide a miss and a diagnostic block cannot.
14. Percutaneous Hydro Resection. Remove it, do not jam it. A jet of water removes the damaged tendon tissue sending the signal, awake and in minutes, where a nerve stimulator only confuses the signal. A bridge until the tendon is loaded.
15. Regenerative Medicine over Band Aids. A steroid buys time at a cost to the joint. Platelet-rich plasma is a seed that only grows in a repaired field. The negative PRP trials come first.
16. Pain in the Elderly. Does she hurt? The quietest patient on a nursing-home floor is often in the most pain, and the chart records half the pain of a person who cannot speak.
17. The Regulatory Environment. A dose is not a diagnosis. A chart number that went from voluntary guideline to health-plan score to pharmacy alert says nothing about what generates the pain. The goal is finding the generator, not zero.
18. Cost Effectiveness in Pain Care. The cheapest costs the most. Blood before scan, block before burn, bridge before fusion.
19. Reframing the Search for the Best Doctor. What the star cannot see. Judge by whether you understood what was wrong, in words you could use, and whether it stayed better.
20. Nociceptive versus Neuropathic Pain. Nerve or joint? A working alarm from tissue, or a nerve that became the generator. The examination that sorts them takes ninety seconds.
21. The Biopsychosocial Reality. Not in your head. Depression is an inflammatory state. Loneliness is a lab value nobody orders.
22. The Individual as the Foundation. The next one is you. Hopelessness is a prognostic factor that can change in a single visit.

Why does pain come back after the injection?

Because the injection was aimed at the joint, and the joint is rarely where chronic pain starts.

Dr. Padda performs the injections and ablations this book examines. He does not argue against them. He argues that they are a bridge: symptom control that buys time and mobility to repair the terrain. Leave the high insulin, the inflammation and the nutrient shortfalls in place, and the pain returns. The next procedure gets booked. Chapter 12 names that loop: the needle became the plan.

What should a pain evaluation actually look at?

The generator and the terrain, in the same visit.

The generator is the structure producing the signal. The terrain is the insulin, the inflammatory load and the nutrient shortfalls that decide how loudly it fires and whether the repair holds. An evaluation that finds only one of the two has done half the job.

How are the Deep Dives different from the book?

The book argues. The Deep Dives show the receipts, claim by claim: the study, its design, who was in it, the number and exactly where it sits in the paper, and what it does not show. Where evidence is mixed, both sides appear at full strength. Where a trial argues against the chapter, that trial is printed too.

Across twenty-two chapters: 2,291 references. They range from 23 pages and 73 references for Chapter 2 to 63 pages and 153 references for Chapter 17. Chapter 16, on pain in the elderly, carries 162.

A book that only gives you the good news is not a book you can trust with your back.

Scan the code at the end of any chapter, or open a chapter on the Deep Dive page and enter your name and email. The PDF arrives within a few minutes. The remaining twenty-one follow one a week, in order.

Is there a video for each chapter?

Yes. All twenty-two chapters have their own video with the chapter's slides, on the Padda Institute channel and on each chapter's Deep Dive page. Start with Chapter 1, The Cost of Pain.

Who wrote The Pained Brain?

Dr. Padda is an interventional pain physician in St. Louis who performs the procedures the book examines from the inside. He directs the Padda Institute, is board certified in interventional pain and pain medicine, and is a Diplomate of the Society of Metabolic Health Practitioners, which covers the terrain half of the argument. He holds full staff privileges at Anderson Hospital in Maryville, Illinois, and is licensed in Missouri and Illinois (NPI 1427035955; Missouri medical license MD 100572). His full record is on the Dr. Gurpreet Singh Padda page. Dr. KrisJay Fucanan, MD, is coauthor.

Can I be evaluated for chronic pain in St. Louis?

Yes. Dr. Padda sees patients in person in St. Louis through the Padda Institute, the practice he has led since 2001. Text (314) 886-5902. For how the practice approaches opioids and the alternatives, see opioid stewardship and non-opioid pain treatment.

Outside the St. Louis area, take the Deep Dives to your own physician. They were written for that.

Frequently asked questions

Why is my pain worse at night?

Chapter 7 explains that the body's own pain control runs on a clock, so pain peaks around three in the morning, and one bad night measurably lowers the pain threshold.

Can my diet cause pain?

Chapter 5 argues yes: the molecules that make an inflamed joint throb are built from the fat you eat, and it covers three randomized trials that cut headache days by changing the plate.

Why did I get carpal tunnel or frozen shoulder without diabetes?

Chapter 6 shows glycation stiffening collagen in tendons and nerve tunnels years before anyone says diabetes.

Should back pain go to the emergency room?

Rarely. Chapter 10 reports that three in a hundred back-pain patients need the emergency room, and that many long-term opioid prescriptions start there.

Is a steroid or PRP injection better?

Chapter 15 compares them: a steroid buys time at a cost to the joint, while PRP only grows in a repaired field. It prints the negative PRP trials first.

How do I choose a pain doctor?

Chapter 19 says to judge by whether you understood what was wrong, whether it was explained in words you could use, and whether it stayed better. A star rating has never been shown to track clinical quality.
