Peripheral Nerve and Muscle Disorders
Numbness, tingling, burning sensations or muscle weakness can have several causes. A neurological assessment can help identify where symptoms are coming from and what investigations or treatment may be useful.
Enquire about a consultationWhat are peripheral nerve and muscle disorders?
Peripheral nerves carry signals between the brain and spinal cord and the rest of the body. Problems affecting these nerves, the nerve-muscle connection or the muscles themselves can cause different patterns of symptoms.
Peripheral neuropathy, a trapped or compressed nerve and certain muscle conditions are examples. Symptoms that seem similar may also arise from the spine or central nervous system, so it is important not to assume the cause before assessment.
Dr Yasser Falah can take a detailed history, carry out a neurological examination and discuss appropriate tests and next steps based on the findings.
Common symptoms
Symptoms vary depending on whether sensory nerves, motor nerves or muscles are affected.
Numbness and tingling
Reduced feeling, pins and needles or altered sensation in the feet, hands or another part of the body.
Burning or shooting pain
Pain that feels hot, electric, stabbing or unusually sensitive to touch.
Muscle weakness
Difficulty gripping, climbing stairs, standing from a chair or lifting the front of the foot.
Balance difficulties
Unsteadiness, especially in poor light or when sensation in the feet is reduced.
Cramps and twitching
Muscle cramps or involuntary twitching, sometimes alongside weakness or fatigue.
Changes in muscle bulk
Visible thinning of a muscle or a change in strength that develops over time.
These symptoms do not point to one diagnosis on their own. Their distribution, timing and progression are often important clues.
What can cause these problems?
Common possibilities include peripheral neuropathy associated with diabetes, vitamin B12 deficiency, compression of an individual nerve and effects of certain medicines.
Other causes include inflammatory nerve disorders, inherited conditions and disorders affecting muscle function. In some cases, investigations do not identify a single underlying cause.
A neurological examination helps distinguish a peripheral nerve problem from a muscle disorder, a spinal problem or another neurological condition.
Recognising urgent symptoms
Call 999 for sudden facial drooping, arm weakness, speech difficulty or sudden one-sided numbness, even if symptoms improve.
Rapidly progressive weakness, difficulty breathing or swallowing, or new severe weakness with bladder or bowel changes requires immediate emergency assessment.
For symptoms that are persistent or gradually worsening, arrange a prompt GP or neurological review rather than waiting for them to become disabling.
Diagnosis and neurological assessment
The most useful investigations depend on your symptoms and examination. Not everyone needs the same tests.
History and examination
Review where symptoms started, how they have changed, medical history and medicines. Examine sensation, muscle strength, reflexes, coordination and walking where relevant.
Blood tests and other investigations
Tests may look for contributing causes such as diabetes, vitamin deficiencies or thyroid problems. MRI or other imaging may be considered when findings suggest a spinal or central cause.
Nerve and muscle testing
Nerve conduction studies and electromyography (EMG) can help assess nerve and muscle function when clinically appropriate. Specialist referrals or further tests may sometimes be needed.
The plan is individual. Nerve conduction studies and EMG are not automatically necessary for every person with tingling or weakness.
How are nerve and muscle symptoms managed?
Management is based on the diagnosis, the effect on everyday life and any treatable contributing factors.
Addressing the cause
Where possible, treatment may focus on an underlying condition, a vitamin deficiency, medicine-related effects or a compressed nerve.
Managing nerve pain
Some people benefit from medicines specifically used for neuropathic pain, alongside a review of sleep, function and treatment response.
Maintaining movement and safety
Physiotherapy, balance support, adaptations or referral to specialist services may help where weakness, falls or impaired function are concerns.
Some nerve and muscle conditions need care from a specialist neuromuscular or multidisciplinary team. Appropriate referral will depend on the suspected diagnosis.
How Dr Yasser Falah can help
Dr Falah is a London-based Consultant Neurologist. His assessment can help establish whether symptoms suggest a peripheral nerve or muscle problem, another neurological condition or a non-neurological cause.
Following examination, he can review previous investigations, explain likely causes, recommend appropriate tests and discuss management or referral where indicated. The aim is a clear plan based on your individual presentation.

Peripheral nerve and muscle disorder FAQs
What causes tingling or numbness in my hands and feet?
Possible causes include nerve compression, peripheral neuropathy, diabetes, vitamin deficiencies and several other conditions. The pattern and examination findings help determine which investigations are appropriate.
Does muscle weakness always mean a serious neurological disease?
No. Weakness has many possible explanations, including pain, injury, nerve problems and muscle conditions. Persistent or progressive weakness should be assessed rather than assumed to have one cause.
What is the difference between neuropathy and a muscle disorder?
Neuropathy affects peripheral nerves and can cause altered sensation, pain or weakness. A primary muscle disorder affects the muscles themselves and more often causes weakness without prominent tingling or numbness.
Will I need nerve conduction studies or an EMG?
Not everyone needs these tests. They may be useful when the examination suggests a peripheral nerve or muscle problem and the results could clarify the diagnosis or guide management.
Can peripheral neuropathy be treated?
Treatment depends on the cause. Some contributing conditions can be addressed, nerve pain can often be managed, and physiotherapy or other support may help with weakness and balance problems.
When should I seek urgent help for weakness or numbness?
Sudden one-sided weakness, facial drooping or speech changes may indicate a stroke and require an immediate 999 call. Rapidly worsening weakness, especially with breathing or swallowing problems, also needs emergency assessment.
