One-liner#

Recognize and manage somatic symptom disorder and functional syndromes by validating symptoms, avoiding excessive testing, maintaining the therapeutic relationship, and addressing underlying psychological factors.

Quick nav#

Red flags / send to ED#

Always rule out organic disease first. Somatic symptom disorder is a diagnosis of inclusion (symptoms are real), not exclusion.

Red flags that warrant further workup:

  • New neurologic deficits
  • Unexplained weight loss
  • Fever
  • Night sweats
  • Abnormal vital signs
  • Objective findings on exam inconsistent with functional diagnosis

The key is proportionate workup—not no workup, but not excessive workup either.

Key history#

Characterize the symptoms:

  • Multiple somatic symptoms or one severe symptom
  • Duration (typically chronic, >6 months)
  • Pattern: constant vs episodic; relationship to stress
  • Prior workups and results
  • Response to prior treatments
  • Impact on function (work, relationships, daily activities)

DSM-5 criteria for somatic symptom disorder:

  • One or more somatic symptoms that are distressing or result in significant disruption of daily life
  • Excessive thoughts, feelings, or behaviors related to the symptoms:
    • Disproportionate and persistent thoughts about seriousness
    • Persistently high anxiety about health or symptoms
    • Excessive time and energy devoted to symptoms
  • Symptoms typically present >6 months

Key point: The diagnosis does NOT require that symptoms be medically unexplained. The focus is on the excessive response to symptoms.

Screen for psychological factors:

  • Depression (PHQ-9)
  • Anxiety (GAD-7)
  • Trauma history (ACEs, PTSD)
  • Life stressors
  • Childhood illness experiences
  • Health anxiety (“Do you worry a lot about having a serious illness?”)

Illness behavior patterns:

  • Doctor shopping
  • Frequent ED visits
  • Requesting specific tests or medications
  • Dissatisfaction with reassurance
  • Symptom amplification with attention

Functional syndromes to recognize:

  • Fibromyalgia: widespread pain, fatigue, sleep disturbance
  • Irritable bowel syndrome: abdominal pain, altered bowel habits
  • Chronic fatigue syndrome: severe fatigue, post-exertional malaise
  • Chronic pelvic pain
  • Tension-type headache
  • Non-cardiac chest pain
  • Functional neurologic disorder (conversion)

Social history:

  • Disability status or pending claims
  • Work situation
  • Relationship stressors
  • Secondary gain (not to dismiss symptoms, but to understand context)

Focused exam#

Thorough but focused exam:

  • Validates patient’s concerns
  • Identifies any objective findings
  • Builds therapeutic alliance

Look for:

  • Objective findings that don’t match reported severity
  • Inconsistencies (e.g., normal gait when observed vs reported inability to walk)
  • Signs of underlying medical disease
  • Signs of depression or anxiety

Functional neurologic signs (if neurologic symptoms):

  • Hoover sign: weakness of hip extension that normalizes with contralateral hip flexion
  • Tremor entrainment: tremor changes frequency when asked to tap with other hand
  • Give-way weakness: sudden collapse of resistance during strength testing
  • Non-anatomic sensory loss

Important: These findings indicate functional neurologic disorder, NOT malingering. The symptoms are real to the patient.

Workup#

Principle: Proportionate workup, not no workup

Initial reasonable workup for unexplained symptoms:

TestRationale
CBCRule out anemia, infection
CMPMetabolic causes
TSHThyroid dysfunction
ESR/CRPInflammatory conditions

Additional based on symptoms:

  • Specific to symptom pattern (e.g., celiac panel for GI symptoms)
  • Guided by exam findings

When NOT to order more tests:

  • Extensive prior negative workup
  • Symptoms unchanged for years
  • No new red flags
  • Testing driven by patient demand rather than clinical indication
  • Each negative test often leads to request for another

How to decline further testing:

  • “I understand you’re worried. Based on your symptoms and exam, I don’t think more tests will give us answers. They might actually cause more worry if we find incidental things.”
  • “I’m confident we’ve ruled out serious disease. More testing isn’t likely to help and could lead to unnecessary procedures.”
  • Offer alternative: “Instead of more tests, let’s focus on helping you feel better.”

Initial management#

Core principles:

  1. Validate symptoms: “Your symptoms are real. I believe you’re suffering.”
  2. Avoid dismissal: Never say “it’s all in your head” or “there’s nothing wrong”
  3. Reframe: “Your nervous system is sending pain signals even though there’s no damage”
  4. Limit testing: Explain why more tests won’t help
  5. Schedule regular visits: Reduces urgent visits and builds relationship
  6. Address psychological factors: Gently introduce connection between stress and symptoms
  7. Set realistic goals: Function improvement, not symptom elimination

What NOT to do:

  • Order every test the patient requests
  • Dismiss or minimize symptoms
  • Abandon the patient (“there’s nothing I can do”)
  • Refer to multiple specialists without coordination
  • Promise that tests will provide answers

Communication strategies:

  • “I take your symptoms seriously”
  • “The good news is we’ve ruled out [serious conditions]”
  • “Your symptoms are real, and they’re caused by how your nervous system is processing signals”
  • “Stress and emotions can cause real physical symptoms—this doesn’t mean you’re making it up”
  • “I want to help you feel better and function better, even if we can’t make symptoms go away completely”

Management by diagnosis#

Somatic symptom disorder#

Education:

  • Symptoms are real, not imagined
  • The brain-body connection is powerful
  • Stress, anxiety, and depression can amplify physical sensations
  • Goal is improved function, not necessarily symptom elimination
  • Treatment takes time and partnership

Treatment approach:

Therapeutic relationship:

  • Schedule regular visits (every 2-4 weeks initially)
  • Brief, focused visits
  • Consistent provider (avoid doctor shopping)
  • Validate symptoms at each visit
  • Gradually introduce psychological framework

Address comorbid psychiatric conditions:

DrugDoseContraindicationsMonitoringCostNotes
SertralineStart 25 mg daily; target 50-200 mgMAOIsNone$If comorbid depression/anxiety
DuloxetineStart 30 mg daily; target 60 mgMAOIs; hepatic impairmentLFTs if concerns$$Good for pain syndromes; SNRI
AmitriptylineStart 10 mg at bedtime; target 25-75 mgCardiac disease; urinary retentionECG if cardiac history$Low-dose TCA; helps pain, sleep; anticholinergic

Psychotherapy referral:

  • CBT most evidence-based
  • Frame as “learning skills to manage symptoms” not “it’s psychological”
  • “Many people with chronic symptoms find that working with a therapist helps them cope better”

Physical therapy:

  • Graded exercise
  • Functional restoration
  • Avoid bed rest and deconditioning

Follow-up: Every 2-4 weeks initially; can space to monthly once stable.


Illness anxiety disorder (hypochondriasis)#

Education:

  • Health anxiety is common and treatable
  • Reassurance-seeking and checking behaviors maintain anxiety
  • Goal is to tolerate uncertainty, not achieve certainty

Treatment:

  • Limit testing and reassurance (paradoxically worsens anxiety)
  • Scheduled visits (reduces urgent visits)
  • CBT highly effective
  • SSRI if severe

Key intervention: Help patient tolerate uncertainty rather than seeking more tests.

Follow-up: Regular scheduled visits; CBT referral.


Fibromyalgia#

Education:

  • Real condition with altered pain processing
  • Not inflammatory or degenerative
  • Exercise is essential (though initially painful)
  • Medications help but don’t cure
  • Multidisciplinary approach most effective

Treatment:

DrugDoseContraindicationsMonitoringCostNotes
DuloxetineStart 30 mg daily; target 60 mgMAOIs; hepatic impairmentLFTs if concerns$$FDA-approved; also helps depression
PregabalinStart 75 mg BID; target 150-225 mg BIDRenal impairment (adjust dose)None$$FDA-approved; sedation, weight gain
MilnacipranStart 12.5 mg daily; target 50 mg BIDMAOIsBP$$FDA-approved; SNRI
AmitriptylineStart 10 mg at bedtime; target 25-50 mgCardiac disease; urinary retentionECG if cardiac history$Off-label; helps sleep and pain
Cyclobenzaprine5-10 mg at bedtimeCardiac disease; MAOIsNone$Muscle relaxant; helps sleep; similar to TCA
GabapentinStart 100-300 mg at bedtime; target 300-600 mg TIDRenal impairmentNone$Off-label; alternative to pregabalin

Non-pharmacologic (essential):

  • Aerobic exercise (start low, increase gradually)
  • Sleep hygiene
  • CBT
  • Stress management

What NOT to use:

  • Opioids (not effective; risk of dependence)
  • NSAIDs (not effective for central sensitization)
  • Benzodiazepines (not effective; dependence risk)

Follow-up: Monthly initially; then every 3 months.


Irritable bowel syndrome#

Education:

  • Common condition; brain-gut connection
  • Not dangerous; doesn’t lead to cancer or IBD
  • Dietary and lifestyle changes help many people
  • Medications can help symptoms

Treatment:

  • Low FODMAP diet trial
  • Fiber supplementation (start low)
  • Antispasmodics: dicyclomine 10-20 mg QID PRN, hyoscyamine
  • For diarrhea-predominant: loperamide PRN
  • For constipation-predominant: PEG, linaclotide, lubiprostone
  • Low-dose TCA (amitriptyline 10-25 mg at bedtime) for pain
  • SSRI if comorbid anxiety/depression

Follow-up: 4-6 weeks after dietary/medication changes.


Functional neurologic disorder (conversion disorder)#

Education:

  • Symptoms are real, not faked
  • The brain is sending incorrect signals
  • This is a recognized neurologic condition
  • Physical therapy is the main treatment
  • Prognosis is often good with proper treatment

Treatment:

  • Explain diagnosis in positive terms: “Your brain is sending the wrong signals, but the good news is this can improve”
  • Physical therapy (specialized in functional disorders if available)
  • Psychology/psychiatry referral
  • Treat comorbid depression/anxiety
  • Avoid unnecessary tests and procedures

What NOT to do:

  • Imply patient is faking
  • Order extensive neurologic workup after diagnosis established
  • Refer to multiple neurologists

Follow-up: Regular visits; coordinate with PT and psychology.

Follow-up#

Schedule regular visits:

  • Every 2-4 weeks initially
  • Brief (15-20 minutes)
  • Focused on function, not symptoms
  • Consistent provider

At each visit:

  • Validate symptoms briefly
  • Assess function (work, activities, relationships)
  • Screen for depression/anxiety
  • Review medication response
  • Reinforce coping strategies
  • Avoid ordering new tests unless clear indication

Return precautions:

  • New symptoms significantly different from usual pattern
  • Red flag symptoms (weight loss, fever, neurologic changes)
  • Worsening depression or suicidal thoughts

When to refer:

  • Psychiatry: severe comorbid psychiatric illness; treatment-resistant
  • Pain specialist: complex chronic pain
  • Neurology: functional neurologic disorder (for diagnosis confirmation)
  • Physical therapy: deconditioning, functional restoration

Disability and work notes:

  • Be honest and specific in documentation
  • Focus on functional limitations, not symptoms
  • “Patient reports difficulty with [specific tasks]” rather than “patient is disabled”
  • Avoid permanent disability determinations if possible; reassess periodically
  • Encourage return to work with accommodations when possible
  • Be aware that disability can reinforce illness behavior
  • If asked to complete disability forms: document what you observe, not just what patient reports

Documentation tips:

  • Document your clinical reasoning for limiting testing
  • Note that you validated symptoms and explained the diagnosis
  • Record patient’s response to explanation
  • Document safety-netting: “Return if [red flags]”
  • If declining requested tests: document the discussion and rationale

Patient instructions#

  • Your symptoms are real, and I take them seriously. We’ve done testing to make sure there’s nothing dangerous causing them.
  • Sometimes the nervous system can become oversensitive and send pain or discomfort signals even when there’s no injury. This is what’s happening with your symptoms.
  • Stress, worry, and mood can make these symptoms worse. This doesn’t mean the symptoms are “in your head”—the mind-body connection is powerful.
  • The goal of treatment is to help you feel better and do more of the things you enjoy, even if symptoms don’t go away completely.
  • Regular exercise, good sleep, and stress management all help. Consider working with a therapist who specializes in chronic symptoms.
  • I want to see you regularly so we can work on this together. You don’t need to wait until symptoms are severe to come in.
