Recognising New Numbness and Tingling for Student Nurses
Learn how to clarify new sensory symptoms, compare them with the patient's normal sensation and recognise when numbness or tingling forms part of a more concerning neurological change.
Clarify exactly what the patient is experiencing
Patients describe altered sensation in many ways. Record their description and establish where the change is occurring.
Reduced or absent feeling
The patient may describe an area as numb, deadened or less sensitive than usual.
Pins and needles
Tingling may be described as prickling, buzzing or an unusual electrical sensation.
Feeling is different
Sensation may still be present but feel unusual or different from the opposite side.
Where is it?
Establish whether the symptom affects the face, arm, hand, leg, foot or a larger area.
One side or both?
New unilateral sensory change can be an important neurological finding.
What can the patient no longer do normally?
Altered sensation may affect grip, walking, coordination or safe use of a limb.
Establish onset and baseline
When did it start?
Establish when the patient first noticed the sensory change.
Sudden or gradual?
Identify whether the symptom appeared abruptly or developed over time.
Is it changing?
Ask whether the numbness or tingling is spreading, improving or becoming more intense.
What is normal?
Establish previous neuropathy, neurological disease, injury or longstanding sensory loss.
Look for associated neurological change
Can the limb move normally?
New sensory change combined with weakness is more concerning than an isolated symptom.
Any new facial change?
Look for facial asymmetry or altered sensation affecting the face.
Any communication change?
Listen for new slurred speech or difficulty producing or understanding language.
Any visual disturbance?
Ask about new double vision, loss of vision or other sudden visual change.
Any new clumsiness?
Look for altered coordination, balance or difficulty controlling movement.
Any reduced responsiveness?
Drowsiness, confusion or deteriorating consciousness increases concern significantly.
Compare sensation carefully
Follow local neurological assessment procedures and work within your competence. The aim is to recognise meaningful differences rather than undertake a specialist neurological examination independently.
Left versus right
Where appropriate, compare similar areas on both sides of the body.
Establish the affected area
Clarify whether altered sensation is localised or affects a broader region.
Use the patient's feedback
Ask whether sensation feels the same, reduced or different between areas.
Assess the whole patient
Airway
Confirm airway patency and identify any immediate threat.
Breathing
Assess respiratory rate, oxygen saturation, breathing pattern and work of breathing.
Circulation
Assess pulse, blood pressure, perfusion and other evidence of deterioration.
Disability
Assess consciousness and relevant neurological findings. Check blood glucose when clinically appropriate.
Exposure
Consider injury, infection and other relevant findings while maintaining dignity.
Escalate
Sudden sensory loss or new sensory change with other neurological abnormalities should be escalated promptly.
When numbness or tingling requires prompt escalation
- Sudden new numbness affecting one side of the body.
- New sensory loss associated with arm or leg weakness.
- Facial numbness with new facial asymmetry.
- New numbness with speech or language disturbance.
- New sensory change with visual disturbance.
- Numbness associated with sudden severe headache.
- New sensory change with significant balance or coordination problems.
- Sensory symptoms with reduced or deteriorating consciousness.
- Rapidly spreading or worsening neurological symptoms.
- Any sensory change occurring as part of wider acute deterioration.
Sensory loss can affect function and safety
Walking may become less safe
Altered sensation in a leg or foot can affect balance and awareness of position.
Grip may be unreliable
Reduced sensation can make handling objects, drinks or mobility aids more difficult.
Reduced sensation may hide injury
A patient may be less aware of pressure, temperature or minor trauma in an affected area.
A patient reports sudden numbness in one arm
Example
A patient suddenly reports that their left hand and arm feel numb and different from the right side.
While assessing them, you notice they are also struggling to lift the same arm as strongly as before and their speech sounds slightly unclear.
You recognise the pattern: new unilateral sensory change + weakness + speech change.
You establish the time symptoms were first noticed, begin an ABCDE assessment and escalate the neurological change promptly according to local procedures.
Describe the sensory change precisely
Example escalation
“I'm concerned about Mrs Roberts. At approximately 13:05 she developed sudden numbness affecting her left hand and arm. This is new for her. Her left arm also appears weaker than earlier and her speech now sounds less clear.”
This communicates the time of onset, area affected, change from baseline and associated neurological signs.
Sensory assessment errors to avoid
- Recording “pins and needles” without establishing the affected area.
- Failing to ask when the sensory change began.
- Not comparing the symptom with the patient's baseline.
- Ignoring whether symptoms affect only one side.
- Assessing sensation without checking strength, speech, face or vision.
- Assuming previous neuropathy explains a sudden new change.
- Performing specialist sensory testing outside your competence.
- Delaying escalation while trying to identify the exact diagnosis.
Clarify → compare → connect → escalate
Understand the symptom
Establish what the patient feels, where it occurs and when it started.
Look for asymmetry and associated signs
Compare with baseline and connect sensory change with weakness, face, speech, vision and consciousness.
Report new neurological change clearly
Communicate the location, onset, progression and associated findings promptly.
New sensory change matters when you connect it with the whole patient
Build confidence by clarifying the symptom, comparing both sides and recognising when numbness or tingling forms part of broader neurological deterioration.
