Peripheral neuropathy

6-minute read

What is peripheral neuropathy?

Peripheral neuropathy is when there is damage to the peripheral nerves. These are the nerves away from the centre of your body, such as those in the hands and feet.

There are 3 types of nerves:

  • sensory nerves carry signals about touch, taste, sight, hearing and smell
  • motor nerves carry signals to help you move
  • autonomic nerves carry signals to help with balance, sweating, digestion and many of the things you do without thinking

Peripheral neuropathy usually affects the sensory nerves in your hands, feet, arms or legs. Some people find it affects only a small part of their body, like a finger or a toe.

But the autonomic nerves and motor nerves can also be damaged.

What are the symptoms of peripheral neuropathy?

Common symptoms of peripheral neuropathy include:

  • pain
  • pins and needles
  • numbness
  • tingling
  • a burning sensation
  • aching, cramps and weakness

Symptoms can be mild or severe. Symptoms often begin in the toes and fingertips and move up towards the knees and elbows. Symptoms are often worse at night.

What causes peripheral neuropathy?

The most common cause of peripheral neuropathy is diabetes, either type I diabetes or type 2 diabetes. This is called diabetic neuropathy.

Other causes of peripheral neuropathy include:

When should I see my doctor?

Call your doctor if you have:

  • weakness and numbness in your hands and feet
  • unusual tingling in your hands and feet
  • pain or a feeling of burning in your hands and feet

How is peripheral neuropathy diagnosed?

Your doctor will:

  • Discuss your symptoms with you and examine you.
  • They might recommend some blood tests to check for things like diabetes or vitamin deficiency.
  • Your doctor might also refer you to a specialist doctor.

Sometimes doctors are not able to find any cause for peripheral neuropathy.

How is peripheral neuropathy treated?

The type of treatment will depend on what is causing the problem.

  • If you have a condition such as diabetes or a vitamin deficiency, your doctor will be advise you to have treatment for that condition.
  • Sometimes there might not be a clear cause.
  • Sometimes there might be a cause but no specific treatment.

If a cause cannot be found, then your doctor will aim to treat the symptoms.

If you have mild pain from peripheral neuropathy, this can usually be controlled with simple pain relief medicines, such as paracetamol and ibuprofen. If you experience more severe pain, you should talk to your doctor about other forms of pain relief. These can include:

Techniques such as psychological therapy may also be required to help manage the pain.

Can peripheral neuropathy be prevented?

This depends on the cause. For example:

  • You can prevent or delay peripheral neuropathy due to diabetes by controlling the sugar levels in your blood.
  • You can prevent or delay peripheral neuropathy due to heavy alcohol use by reducing the amount of alcohol you drink.

Other neuropathies, such as hereditary neuropathy, cannot be prevented.

Complications of peripheral neuropathy

Some complications of peripheral neuropathy include:

  • burns and skin injuries because of numbness
  • infections
  • falls because of numb feet
