Numbness, Altered Sensation, and Hypersensitivity

Functional sensory symptoms can include too little sensation, too much sensation or a sensation that feels changed. The experience is real even when routine tests do not show tissue damage. (*citations* [1](#citation-1))

For the Person With FND

Definition

Altered sensation means touch, temperature, pain, body position or another feeling is experienced differently. Numbness is reduced sensation. Hypersensitivity is an unusually strong or distressing response to sensory input.

Three body outlines are labelled less feeling, altered feeling and over-sensitive feeling.

Illustration: a person’s sensory map can vary; this is not a self-diagnostic chart.

If you read only one thing

Sensory symptoms deserve a careful history and examination. Older bedside signs should not be used alone to decide that a symptom is functional.

What this may feel like

People describe pins and needles, burning, coldness, heaviness, a missing body part, an altered boundary or pain from ordinary touch. Symptoms may be steady or change with position, activity, attention, migraine, fatigue or other health conditions.

Functional sensory symptoms can coexist with neuropathy, migraine, nerve injury, medication effects and other causes. A new distribution, injury, weakness or major change needs appropriate assessment.

What may help

An occupational therapist or physiotherapist may explore safe ways to use touch, texture, movement, vision and meaningful activity. Access strategies can reduce immediate load. Rehabilitation may gently expand tolerance or improve use of the affected area. These are different goals and can be combined. [2][3]

Avoid aggressive rubbing, extreme temperatures or repeated checking of an area with reduced sensation. Protect skin and follow advice for any separate medical condition.

Community experiences for review

These accounts show sensory variety and a practical adaptation. They are lived experience, not treatment evidence.

Option 1 — several sensations at once

“I get tingling, needles, numbness, and burning sensations.”

— The writer listed multiple sensory symptoms within a broader FND experience. Read the public source.

Option 2 — occupational therapy and daily function

“My OT helped me … learn exercises to calm myself and avoid sensory overwhelm.”

— The writer also described a prescribed sensory routine as helping them stay within a tolerable range. Read the public source.

Questions

Which sensation is hardest to live with, and what does it stop or interrupt?

Do you need less sensory load now, greater tolerance over time, or both?

One small thing you can do

Choose one safe adjustment, such as a softer fabric or moving an irritating object. A lower-demand version is to name one sensory barrier in your day.

Stop any experiment that causes pain, skin damage, dizziness or a lasting flare. Seek assessment for a new or substantially changed pattern.

For Family, Friends, and Other Supporters

Ask before touching an affected area or changing the environment. A light touch may feel painful, while numbness may hide pressure or heat injury. Help with skin checks or practical changes only if the person wants this.

Do not repeatedly test sensation or insist on exposure. Support immediate access and any clinician-guided rehabilitation as separate, chosen needs.

Research quotations for review

Option 1 — Nielsen et al., 2026

“We currently lack data on the prevalence, impact and prognosis of sensory symptoms in FND.”

Option 2 — McCombs et al., 2024

“limited research has been conducted to examine the efficacy of OT interventions for FND.”

Do not overstate bedside signs or treatment evidence

Map the symptom and its functional effect, then assess relevant neurological, peripheral-nerve, migraine, pain, dermatological and medication-related alternatives. The 2026 case-control study found limits in classic signs such as midline or vibration splitting; avoid using one sign as proof. [1]

Clarify whether the goal is protection, accommodation, functional use, desensitization or another chosen outcome. McCombs and colleagues reported preliminary outcomes from an uncontrolled retrospective cohort; frame sensory-based OT as emerging evidence, not established cure. [2][3]

Research and Sources

The sensory case-control study directly examines diagnostic signs. The OT sources offer consensus and preliminary observational evidence, so causal treatment claims would be premature. [1][2][3]
