In the thick of the opioid epidemic, there is this widespread fear called “opiophobia,” which basically means people, including patients and doctors, are scared to use opioids even when they are really needed for serious medical issues. This fear comes from the idea that even a short stint on opioids for acute pain, like after surgery, often leads to addiction or worse. John A. Bumpus’s 2025 review in ACS Pharmacology …

The truth about short-term opioid prescribing and opioid use disorder
Spinal cord stimulation (SCS) continues to be a solid option for people dealing with chronic pain that just will not budge with the usual approaches like medications, physical therapy, or injections. It is a minimally invasive way to deliver low-level electrical pulses through electrodes placed in the epidural space near the spinal cord, helping to change how pain signals reach the brain and often providing relief in areas like the …

How spinal cord stimulation offers relief for chronic pain
The real magic in chronic pain care isn’t just the pills or the procedures, but it’s the connection between doctor and patient. When a physician shows genuine empathy and truly listens, patients feel seen, trust deepens, and outcomes improve in ways that often outshine standard treatments. Take this striking study: Among more than 1,400 people with chronic low back pain, those cared for by highly empathic doctors ended up with …

Why patient-centered care transforms chronic pain management
A systematic review was conducted following PRISMA 2020 guidelines. Databases (PubMed, Embase, Scopus, Westlaw, LexisNexis) and gray literature were searched from January 2010 to November 2025 using terms related to medical board discipline, pain management, and overreach. Eligibility included studies, legal cases, and reports on disciplinary actions, due process violations, or consequences for physicians/patients.
Findings of 1,847 records, 42 were included (28 journal articles, eight legal cases, six reports). Key abusive …

How punitive board tactics are harming pain management physicians
As a pain physician with over 20 years of experience treating patients with chronic pain, I hear the same plea almost every day: “Doctor, it hurts, please help.”
As an author and patient advocate, I wanted to verbalize the daily reality of chronic pain.
Chronic pain affects an estimated 24.3 percent of U.S. adults (approximately 60 million people) as of 2023, with 8.5 percent (about 21 million) experiencing high-impact chronic pain that …

Chronic pain management: Balancing relief and regulation
In Northern California and beyond, health care systems are rapidly integrating artificial intelligence (AI) and digital tools to transform how pain is recognized, measured, and managed. From algorithm-guided assessments to wearable sensors and predictive analytics, these tools promise to augment clinical decision-making and improve patient outcomes. Yet significant controversies remain, including concerns over algorithmic accuracy, bias, data privacy, and the extent to which technology should complement or potentially displace human …

AI in pain assessment: Balancing innovation with patient safety
As a pain physician, I spend my career advocating for patients who struggle to access appropriate pain management. I write often on hurdles like restrictive opioid policy, excessive regulatory scrutiny, prior authorization, and administrative burdens that detract from patient care. Yet nothing prepared me for the visceral reality of being the patient on the other side of the system.
From physician advocate to patient in the system
My recent experience, unrelated to …

Why doctors struggle with health care system delays
Close your eyes and imagine a health care system that truly prioritizes patients above all else, one that is free from political interference, financial incentives, or secondary gains that distort decision-making. In this ideal framework, regulatory bodies such as the Medical Board, Centers for Disease Control and Prevention (CDC), and Drug Enforcement Administration (DEA) would enforce guidelines uniformly and based on evidence, without inadvertently inflating costs or compromising care quality …

The hidden cost of medical board regulation and prosecutorial overreach
In our diverse world, where everyone sees things through their own lens, shaped by life experiences, beliefs, and facts, chasing after one absolute “truth” often sparks arguments instead of solutions. But what if we aimed for something better: a “shared truth”? This is about coming together, respecting each other’s opinions, and teaming up to find common ground that works for everyone. It’s like turning a debate into a friendly conversation, …

What is shared truth and why does it matter?
California’s opioid policies reveal a stark hypocrisy, imposing draconian restrictions on prescriptions for chronic pain patients (leaving wildfire survivors and others in unrelenting agony) while allocating over $100 million annually through initiatives like the California Harm Reduction Initiative (CHRI) and Proposition 36 to provide free needles, pipes, and fentanyl test strips to addicts with minimal oversight. This disparity is compounded by the Medical Board of California’s (MBC) overreach, where physicians …

California’s opioid policy hypocrisy
As a pain management specialist, my intent is not to promote unchecked opioid prescribing or overlook the serious risks these medications pose. Instead, I advocate for viewing the full picture in patient care. Physicians, trained in medicine and its side effects, must be empowered to use their knowledge and direct observations, including subtle cues like body language and patient interactions during brief visits, to make tailored decisions. Documentation in charts …

Rethinking opioid prescribing policies
Introduction: a crisis of pain
The opioid crisis is one of the most significant public health emergencies of our time, defined by staggering rates of addiction and overdose. Yet, behind the headlines is a story of profound and often overlooked human suffering. In an effort to save lives, public health policies were enacted to aggressively reduce opioid prescriptions. While well-intentioned, these policies have inadvertently precipitated a parallel crisis of iatrogenic harm, …

The opioid crisis’s other victims
The ongoing opioid crisis, claiming over 70,000 lives annually in the U.S. according to the CDC’s 2023 data, presents a perplexing scenario where regulatory bodies, in their attempt to curb misuse, have inadvertently intensified challenges for health care providers and patients. The Centers for Disease Control and Prevention (CDC) issued its 2016 guideline for prescribing opioids for chronic pain, with revisions in 2022 to address misapplications, yet these efforts have …

How restrictive opioid policies worsen the crisis
Imagine a dedicated physician, after years of rigorous training and countless lives saved, facing a medical board complaint over a minor issue—perhaps a clerical error in documentation or a subjective interpretation of a clinical decision. What should be a straightforward matter escalates into a career-threatening ordeal. State medical boards, endowed with significant authority, often wield it with little accountability. Armed with prosecutors who prioritize winning over truth, boards can distort …

Why reforming medical boards is critical to saving patient care
Pain management physicians, who often prescribe controlled substances like opioids, face intense scrutiny. Critics argue that investigations are overly aggressive, resembling fishing expeditions where investigators search broadly for any evidence of wrongdoing, often beyond the original complaint. A 2023 Los Angeles Times report noted that nearly 10,000 investigations were conducted in 2021–2022, with pain physicians disproportionately targeted due to outdated guidelines predating modern evidence-based practices. For example, the reliance on …

Why pain doctors face unfair scrutiny and harsh penalties in California
In principle, the judicial system is founded on fairness, requiring that guilt or innocence be established based on evidence.
All parties including judges, defendants, and plaintiffs should be engaged in a rigorous process of fact presentation and scrutiny.
However, in stark contrast, political systems often prioritize rule manipulation and fact distortion, seeking validation over truth. This critical distinction between politics and jurisprudence becomes dangerously blurred when examining the conduct of medical boards …

Why medical boards are facing growing backlash for abusing power
Theft, in its essence, is the unlawful taking of something valuable from another. While usually associated with material possessions, it also extends to intangible assets such as time, reputation, and emotional well-being. When authorities like medical boards or the Department of Justice (DOJ) engage in unfair practices grounded in presumptive guilt, they are not just misusing their roles but actively stripping individuals of these invaluable resources—an abuse of power that …

Time theft: the unseen harm of abusive oversight
Health care regulatory bodies have embraced a dangerous “accuse first, prove later” strategy that is eroding the foundation of our health care system. Physicians, the bedrock of patient care, are being subjected to accusations based on flimsy, illegitimate reports or random audits. Rather than building cases on substantial initial evidence, these authorities thrive on retrospective scrutiny—analyzing old notes, reframing past actions, and bending interpretations of guidelines to validate their accusations. …

How regulatory overreach is destroying innovation in U.S. health care
In recent years, an alarming trend has emerged within the health care system, one that is eroding the very backbone of medical care delivery: the physician. What once were rules and regulations designed to protect and elevate the standard of medical care are increasingly being exploited by medical authorities as a tool to extort, reprimand, and harass physicians. More disturbingly, this extortion is now cloaked as “education,” forcing doctors to …

The weaponization of rules: How regulatory overreach puts physicians and health care at risk
The health care system, in theory, operates on one fundamental principle: to prioritize patient welfare. Yet, contemporary systems in many regions, particularly the United States, have increasingly veered off course, entangling themselves in a jungle of bureaucracy, regulation, and profit-driven motives that obscure the vital role patients play as the focal point of care. The result is a system riddled with inefficiencies, frustration, and barriers to optimal health care delivery.
