Tingling fingers, numbness in the legs, reduced grip strength, or unexplained weakness are symptoms many people may dismiss as fatigue, posture related strain, or simply part of ageing. However, in some cases, these symptoms may suggest underlying nerve compression or nerve damage that should not be ignored.
As part of his appearance on CNA938’s Wellness Hour with host Ms Cheryl Goh on 12 May 2026, Dr Colum Nolan, Senior Consultant Neurosurgeon and Medical Director of Oxford Spine & Neurosurgery Centre, discussed the topic Silent Nerve Damage: Symptoms That Should Not Be Ignored, highlighting why early recognition and timely assessment may help reduce the risk of long term neurological complications.

When Symptoms May Suggest More Than Fatigue
According to Dr Colum, symptoms become more concerning when they are persistent, progressive, or follow a nerve related pattern rather than improving with rest.
Examples may include:
- Tingling or pins and needles sensations
- Persistent numbness
- Reduced grip strength
- Dropping objects unexpectedly
- Weakness in the arms or legs
- Symptoms affecting one side of the body
- Pain or numbness travelling down the arm or leg
These symptoms may suggest irritation or compression of a nerve rather than simple muscle fatigue.
How Spine Conditions Can Affect Nerves
Slipped Disc
A slipped or herniated disc may press on a nearby nerve root, causing symptoms such as pain travelling down the leg, numbness, or weakness.Spinal Stenosis
Spinal stenosis refers to narrowing around the spinal canal or nerves. As the space tightens over time, pressure on the nerves may gradually increase.Cervical Myelopathy
This occurs when the spinal cord in the neck becomes compressed. More advanced cases may affect:- Hand coordination
- Walking balance
- Dexterity
- Fine motor control
Not All Nerve Damage Comes From the Spine
Dr Colum also highlighted that not all nerve related symptoms originate from spinal conditions.
Medical conditions that may affect peripheral nerves include:
- Diabetes
- Vitamin B12 deficiency
- Thyroid disorders
- Certain autoimmune conditions
- Medication related nerve effects
In some patients, symptoms may initially appear mild and progress gradually over time if the underlying cause is not identified early.
Warning Signs That Should Not Be Ignored
Certain neurological symptoms may require more urgent medical evaluation.
These include:
- Progressive weakness
- Foot drop
- Worsening hand weakness
- Loss of hand dexterity
- Balance problems
- Repeated falls
- Changes in bladder or bowel control
These symptoms may suggest more significant nerve root or spinal cord compression and should not be ignored.
How Doctors Assess Nerve Damage
Diagnosis usually begins with a neurological and clinical assessment to evaluate:
- Muscle strength
- Sensation
- Reflexes
- Coordination
- Walking balance
Imaging tests such as MRI scans help visualise the spine, discs, nerves, and spinal cord in greater detail. In some cases, nerve conduction studies may also be used to determine:
- The exact location of nerve involvement
- Whether symptoms originate from the spine or peripheral nerves
- The severity of nerve dysfunction
Can Early Treatment Help Prevent Long Term Damage?
According to Dr Colum, early treatment may help reduce nerve irritation and support recovery before symptoms become more severe.
Depending on the condition, conservative management may include:
- Physiotherapy
- Medication
- Posture and ergonomic correction
- Activity modification
However, progressive weakness, worsening dexterity, or bladder symptoms may require more urgent specialist evaluation.
Why Early Detection Matters
When nerve compression or neuropathy is left untreated for prolonged periods, patients may develop:
- Chronic nerve pain
- Persistent numbness
- Muscle weakness
- Reduced grip strength
- Walking difficulties
- Long term functional impairment
In more severe cases involving spinal cord compression, some neurological deficits may not fully recover even after treatment.
As highlighted during the CNA938 interview, early recognition and assessment remain important in helping reduce the risk of permanent nerve damage and preserving long term neurological function.
