Functional Disorders, Somatic Symptoms and Chronic Pain (Jones, 8/5/2026)

 A recording of this presentation is available HERE

Thanks to Dr. Kendall Jones for a fantastic opener for R3/Senior Grand Rounds presentation this week. She borrowed from a lecture she attended last spring at the Family Medicine Colloquium by Kaiser Family Medicine teachers. . .but really brought it home to our patient population. 

If you are a primary care clinician caring for patients with functional disorders (think IBS, migraine, fibromyalgia. . .and all those unn-nameable conditions), you should watch this!

Functional Disorders

Medical school trains us well to investigate mechanical/structural abnormalities (e.g. SBO, carotid stenosis, hip fracture), assess for biochemical abnormalities (e.g. low hb, elevated a1c, hyperthyroidism), but does not prepare us for functional disorders-- which, by definition, have no specific tests. Functional disorders are diagnosed with symptom assessments, validated tools, in combination with negativing imaging/labs or other work-up. 

And yet, in primary care, we see a LARGE number of patients with functional disorders. Here are a few:

These patients are challenging. They bring up a lot in clinicians, and they don't always get the care they need. Sometimes they are left to steer their own ship (which doesn't reliably make them better), they get HUGE work ups (all of which turn out negative or equivocal), and they get labels that do not really apply, labels that are hard to remove. 

Dr. Jones reminded us that we use clinical judgement all the time to make diagnoses-- think a viral URI or a migraine. For these patients, we use illness scripts and confidence in our experience. This same notion applies to patients with functional disorders.

Central Sensitization

Central sensitization is a state of persistent CNS hyper excitability in which the brain and spinal cord amplify incoming signals beyond their objective magnitude. The "volume of the nervous system" is literally turned up. This is not psychological. It is driven by neuroinflammation, HPA axis dysregulation, synaptic plasticity in the dorsal horn, reduced descending inhibition, and more. This phenomenon is propagated via ACEs, chronic stress, trauma, perception, expectation, and neuroplasticity. 

I LOVE this fire alarm analogy!

Reminder: our job is NOT to keep searching for a fire.

We need to be able to recognize patterns of central sensitization:

• multi-system symptoms with no unifying biomedical lesion (though don't forget connective tissue and EDS)
• severity out of proportion to objective findings-- the gap is the signal amplification
• symptoms fluctuate with stress, sleep
• prior extensive negative work up but patient remains symptomatic
• presence of ACEs or chronic stress (which patient may not have insight into)
• hypervigilance: symptom tracking, googling, frequent visits, lots of messages
• sensory hypersensitivity: light, sound, temperature, touch, odors (more than just pain)

Language matters

When tests come back negative, avoid "everything is fine", "your tests are normal", "nothing is wrong", "maybe you're stressed". These statements do not explain what IS happening for the patient and leave them searching for another explanation. 

Communication is key!

Remember patients can have central sensitization AND something else!!!

Validated Tools for assessing for Central Sensitization include:

• Somatic Symptom Scale - 8. Gierk B et al. JAMA Intern Med. 2014.

• Eight items rated 0-4 over the past 7 days (GI, back pain, limb/joint pain, HA, CP/SOB, dizziness, fatigue, sleep)

• 8-11 = medium, 12-15 = high, 16-32 = very high.

• Each category increase is associated with 53% more healthcare visits

• CSI: Central Sensitization Inventory. Mayer TG et al. Pain Pract. 2012; Neblett R et al. J Pain. 2013

• Part A: 25 items, scored 0-100 

• Part B: Prior CSS diagnoses (unscored, clinical context)

• Cutoff ≥ 40: 81% sensitivity, 75% specificity for CS syndromes

• <30 = subclinical, 30-39 = mild, 40-49 = moderate, 50-59 = severe

Treatment of Central sensitization:

Education: normalize, reframe: "Your symptoms make sense to me. Let's try to understand what is going on." Discuss the context/ask the question: "What do you think is making your nervous system so sensitive?" Help change their relationship with their symptoms-- to decrease their fear. Remember, having somatic symptoms is part of living inside a body.

Nervous system retraining: mindfulness based pain reduction, breathing exercises, cold exposure (resets the mamalian dive reflex), singing, humming, yoga, meditation, massage (feet and neck)

Central sensitization and Chronic pain

• nociplastic pain happens over months to year; it can be at least partially reversed with desensitization of the oversensitized alarm
• patients have to be patient (months to years) to notice improvement
• patients and physicians benefit from moving away from "symptoms" into acceptance, understanding an rehabilitation>> goal is improving quality of life and increasing function
• movement is key: motion is lotion

Primary care needs united partnership with specialists.

We don't need to get it all done in one visit, even 2 minutes can help shift mindsets

We are not just asking patients to relax, we are helping them re-calibrate their nervous system.

Central sensitization does not invalidate the patient's experience, it only offers an explanation with evidence-based interventions.

Clinicians must NOT miss red flags

Trauma Informed Care (Lund, 3/26/2025)

  A recording of this presentation is available HERE. 

Thanks so much to Dr. Erin Lund for a very impactful presentation this week on Trauma Informed Care. I have to confess that I have seen this presentation (or a previous version) before, but I DO need to hear and rehear and rehear this topic. 

If you remember nothing else, take pearl in: In our daily work should use "universal trauma principles" with ALL patients and then add "extra carefuly trauma informed care" with those whom we KNOW have had extra trauma. 

This includes things like asking for consent, empowering patients over their own bodies and histories, and resisting retraumatization.

I love/hate this image she shared, reminding us of the context of trauma that extends far beyond a person's individual experience. The medical trauma many of our patients have experienced primes them to respond in particular ways to our care provision, and we need to be prepared, but the collective and structural trauma is also ever present.

Trauma abounds. 

Many of us are well-versed in the original Adverse Childhood Events (ACES) study, which found that 61.7% of CA adults had experienced at least one ACE, and 1 in 6 (16%) had experienced 4+ ACES. You can see the most common ACEs in the image below.

But trauma doesn't end in childhood. Adult traumatic experiences are also common; these include: intimate partner violence, gun violence, sexual assault, incarceration, birth trauma, accidents, racism, sudden loss of a loved one, and more. 

The actual "traumatic experience or incident" matters much less than how we respond to the trauma. What are our resources? Do we have resilience? What are our protective patterns? Do we have time to recover?

The image below is a schematic of a stress trigger, the natural response, and then what follows. Note the time of calming down, depletion and recentering. If we have the tools to pass through these stages, we can recover from the trigger. If not, we may not be able to. Traumatic experiences can lead to developing toxic stress physiology. And repeated stress can impact our neurodevelopment, interfering with executive function

Toxic Stress and Caring Adults - KABOOM!

 
A local non-profit does trainings/workshops to promote resilience. In their workshops, they teach us that our protective patterns, which we develop over time, can be helpful and keep us safe. But when overused or used in incorrect situations, they can be harmful, self-destructive, and inhibit connection with others. Those patterns are seen in the slide below:

SAMSHA (2021) says that to be trauma-informed we must 1) Realize the widespread impact of trauma and understand potential for recovery 2) Recognize the signs/symptoms of trauma 3) Respond by integrating this knowledge about trauma into policies and procedures and practices and 4) Seek to active Resist retraumatization. 

We can create a safe context, restore power, value individuals. We can use universal trauma precautions and stay patient-centered. Being trauma-informed in the medical setting involves empowering patients, giving choice when we can, collaborating, offering safety and trustworthiness. In addition, get curious, learn the back story, listen to patients' fears. Ask yourself and the patient, "How can we help you get through this?"

Resilience is protective. I very much recommend you listen to Dr. Lund's presentation, where she goes on to really talk about heartfelt listening, growing empathy to connect, not defining people by their trauma, and making a real difference through trauma-informed care. 

She ended her presentation with a seminal paper on Trauma informed care in the ED from Ashworth et al (2023). A link to that paper and very helpful tables is available HERE.
