Experiences with

Peripheral neuropathy

Peripheral neuropathy develops when nerves in the body's extremities, such as the hands, feet and arms, are damaged. The symptoms depend on which nerves are affected.

In the UK it's estimated almost 1 in 10 people aged 55 or over are affected by peripheral neuropathy.

The peripheral nervous system

The peripheral nervous system is the network of nerves that lie outside the central nervous system (the brain and spinal cord).

It includes different types of nerves with their own specific functions, including:

sensory nerves – responsible for transmitting sensations, such as pain and touch
motor nerves – responsible for controlling muscles
autonomic nerves – responsible for regulating automatic functions of the body, such as blood pressure and bladder function

The main symptoms of peripheral neuropathy can include:

numbness and tingling in the feet or hands
burning, stabbing or shooting pain in affected areas
loss of balance and co-ordination
muscle weakness, especially in the feet

These symptoms are usually constant, but may come and go.

When to see a GP

It's important to see your GP if you experience the early symptoms of peripheral neuropathy.

These include:

pain, tingling or loss of sensation in the feet
loss of balance or weakness
a cut or ulcer on your foot that's not getting better

It's also recommended that people at highest risk of peripheral neuropathy, such as people with diabetes, have regular check-ups.

A GP will ask about your symptoms and may arrange some tests to help identify the underlying cause.

You may be referred to hospital to see a neurologist, a specialist in health problems affecting the nervous system.

Generally, the sooner peripheral neuropathy is diagnosed, the better the chance of limiting the damage and preventing further complications.

In the UK diabetes (both type 1 and type 2) is the most common cause of peripheral neuropathy.

Over time, the high blood sugar levels associated with diabetes can damage the nerves.

This type of nerve damage is known as diabetic polyneuropathy.

Peripheral neuropathy can also have a wide range of other causes.

For example, it can be caused by:

physical injury to the nerves
a viral infection, such as shingles
a side effect of certain medicines or drinking too much alcohol

People who are known to be at an increased risk of peripheral neuropathy may have regular check-ups so their nerve function can be assessed.

Treatment for peripheral neuropathy depends on the symptoms and underlying cause.

Not all of the underlying causes of neuropathy can be treated.

For example, if you have diabetes, it may help to gain better control of your blood sugar level, stop smoking and cut down on alcohol.

Nerve pain may be treated with prescribed medicines called neuropathic pain agents, as standard painkillers often do not work.

If you have other symptoms associated with peripheral neuropathy, these may need to be treated individually.

For example, treatment for muscle weakness may involve physiotherapy and walking aids.

Complications of peripheral neuropathy

The outlook for peripheral neuropathy varies, depending on the underlying cause and which nerves have been damaged.

Some cases may improve with time if the underlying cause is treated, whereas in some people the damage may be permanent or may get gradually worse with time.

If the underlying cause of peripheral neuropathy is not treated, you may be at risk of developing potentially serious complications, such as a foot ulcer that becomes infected.

This can lead to gangrene if untreated, and in severe cases may mean the foot has to be amputated.

Peripheral neuropathy may affect the nerves controlling the automatic functions of the heart and circulation system (cardiovascular autonomic neuropathy).

You may need treatment to increase your blood pressure or, in rare cases, a pacemaker.
