How should I evaluate and manage an adult woman with chronic anxiety who presents with burning and tingling paresthesias in the hands and feet that markedly improve with distraction (e.g., while working, exercising, or socializing) and has a normal neurological exam and laboratory studies?

Evaluation and Management of Distraction-Responsive Paresthesias in an Anxious Patient

Primary Recommendation

This clinical presentation—burning and tingling paresthesias that markedly improve with distraction (work, exercise, socializing) in a patient with chronic anxiety and normal neurological workup—is consistent with functional neurological disorder (FND) with sensory symptoms, and treatment should focus on anxiety management and sensory grounding techniques rather than further neurological investigation. 1, 2

Diagnostic Framework

Key Clinical Features Supporting FND

• Symptom variability with attention: The dramatic improvement during distraction is a hallmark feature of functional sensory symptoms, as these symptoms are modulated by attentional focus and cognitive engagement 1, 2
• Normal neurological examination and laboratory studies: This excludes structural or metabolic causes and supports the FND diagnosis 2
• Comorbid anxiety: Anxiety commonly acts as both a precipitating and perpetuating factor in FND sensory manifestations 1, 2

Understanding the Mechanism

• Your patient may be experiencing "panic without panic" or alexithymia—where physiological anxiety manifests as somatic symptoms (paresthesias) without conscious emotional awareness of anxiety 1, 2
• The improvement with distraction occurs because engagement in activities redirects attention away from internal sensory monitoring, breaking the cycle of symptom focus and amplification 1

Treatment Algorithm

First-Line: Anxiety Management (Primary Target)

Address anxiety as the primary therapeutic target, as it initiates and sustains the sensory symptoms 2:

• Patient education: Explain the physiological fight-or-flight response and how anxiety produces real physical sensations including paresthesias, validating that symptoms are genuine while reframing their origin 1, 2
• Breathing techniques: Teach diaphragmatic breathing to reduce physiological arousal 1
• Progressive muscle relaxation: Implement systematic relaxation protocols 1
• Regular cardiovascular exercise: Prescribe structured aerobic activity, which has moderate effect sizes for anxiety reduction 2
• Cognitive reframing and mindfulness: Help identify how anxiety interacts with sensory symptoms 1, 2

Second-Line: Sensory Grounding Techniques

Implement sensory grounding strategies to prevent dissociation and maintain present-moment awareness 1, 2:

• Environmental focus: Direct attention to external details (colors, textures, sounds in the environment) 1
• Cognitive distractors: Use counting backwards, word games, or singing 1
• Tactile anchoring: Employ textured items or controlled sensory input 1

Third-Line: Graded Desensitization

• Address hypersensitivity directly to prevent it from becoming a maintaining factor through avoidance behaviors 2
• Graded exposure protocols adapted from chronic pain management can build tolerance to sensory stimuli 2

Pharmacological Consideration

• If anxiety management alone is insufficient: Consider selective serotonin reuptake inhibitors (SSRIs) such as escitalopram or duloxetine, which have demonstrated efficacy for generalized anxiety disorder 1, 3
• Fluoxetine has shown benefit specifically for psychogenic paresthesias in case reports 4

Critical Clinical Pitfalls to Avoid

What NOT to Do

• Do not provide constant reassurance: This paradoxically reinforces symptom persistence and increases symptom focus 1, 2
• Do not pursue extensive additional neurological testing: With normal exam and labs, further investigation risks iatrogenic harm by suggesting undetected pathology 2
• Do not dismiss symptoms as "purely psychological": This undermines care and impedes treatment engagement 2

Counterintuitive Finding

• For high-anxiety patients, attention to sensations may be more beneficial than distraction in controlled therapeutic settings: Research shows that among health-anxious individuals, structured attention to physical sensations during therapy sessions resulted in lower anxiety and pain compared to distraction, as it provides short-term anxiety reduction through controlled exposure 5, 6
• However, in daily life, natural distraction through meaningful activities (work, exercise, socializing) remains therapeutic as your patient has already discovered 1

Monitoring Strategy

• Screen routinely for anxiety and depression using validated instruments, given the high comorbidity 1, 2
• Track somatic symptom burden longitudinally with tools like the Patient Health Questionnaire-15 (PHQ-15) 2
• Optimal screening intervals are unknown; use clinical judgment to determine frequency 1

Explaining the Diagnosis to Your Patient

Frame the explanation as follows: "Your symptoms are real and caused by how your nervous system is processing sensory information when you're anxious. The fact that they improve dramatically when you're engaged in activities you enjoy shows that your nervous system is functioning normally—it's just stuck in a pattern of heightened alertness. We can retrain this pattern through specific techniques that reduce anxiety and redirect your attention, similar to how your symptoms already improve naturally when you're busy."
