Neuropathy causes, symptoms & treatment Options

You feel a burning sensation in your feet at night. A strange tingling in your hands that comes and goes. Sharp, shooting pain that seems to have no clear cause. These are classic signs of neuropathy, not random complaints. Peripheral neuropathy affects around one in ten people over the age of 55 in the UK, yet it is frequently misunderstood, misdiagnosed, or simply dismissed.

This guide describes neuropathy in detail, including its causes, symptoms, and, most importantly, treatment options.

What is neuropathy?

Neuropathy, also known as peripheral neuropathy, is the result of damage to or malfunction of the peripheral nerves, which are the extensive network of nerves outside the brain and spinal cord. These nerves carry signals between your brain, spinal cord, and the rest of your body. When they malfunction, those signals get distorted, blocked, or amplified in painful ways. There are three main types of peripheral nerves affected:

• Sensory nerves: which carry feelings of pain, temperature, and touch
• Motor nerves: which control muscle movement
• Autonomic nerves: which regulate automatic functions like heart rate and digestion

Common causes of neuropathy

Neuropathy rarely appears without a reason. Understanding the underlying cause is essential because treating the root cause is often the most effective way to slow progression or reverse damage. Here are the most significant causes seen in the UK.

1. Diabetes

Diabetic neuropathy is the most common form of peripheral neuropathy in the UK. High blood sugar over time damages the small blood vessels that supply your nerves, gradually starving them of oxygen and nutrients.

Around half of all people with diabetes will develop some form of neuropathy during their lifetime. The "glove and stocking" distribution pattern describes how it typically starts in the feet and legs and moves upward.

Key facts:

• Poor blood sugar control significantly accelerates nerve damage
• Symptoms can appear years before a diabetes diagnosis
• Early intervention can slow or halt progression
• Regular foot checks are essential for anyone with diabetes

2. Vitamin deficiencies

Nerves need specific nutrients to function and repair themselves. Peripheral neuropathy can be directly caused by deficiencies in vitamins B1, B6, B9, and, most importantly, B12. This is increasingly common in the UK, particularly among older adults, vegans, and people taking long-term metformin for diabetes.

Key facts:

• B12 deficiency neuropathy is entirely reversible if caught early
• Symptoms of B12 deficiency can take years to become obvious
• A simple blood test can identify the deficiency
• Treatment involves B12 injections or high-dose supplements

3. Alcohol misuse

Chronic alcohol misuse damages nerves directly through its toxic effects, and indirectly through the poor nutrition that often accompanies heavy drinking. Alcoholic neuropathy typically affects the legs first and can be severe.

Key facts:

• Symptoms often improve significantly with alcohol reduction or abstinence
• Thiamine (B1) supplementation is a critical part of treatment
• The damage can be permanent if left unaddressed for too long
• Pain, weakness, and balance problems are the most common features

4. Autoimmune conditions

Conditions like rheumatoid arthritis, lupus, Sjögren's syndrome, and Guillain-Barré syndrome can cause the immune system to mistakenly attack the peripheral nerves. Inflammation and antibody damage disrupt nerve function over time.

Key facts:

• Neuropathy may be the first noticeable symptom of an underlying autoimmune condition
• Treatment targets the immune system disorder, not just the nerve pain
• Immunosuppressant medicines are sometimes needed
• Symptoms can fluctuate significantly depending on disease activity

5. Infections

Several infections can trigger neuropathy either directly or through the immune response they provoke. One of the most prevalent is shingles (herpes zoster), which can result in postherpetic neuralgia, a painful nerve condition that lasts long after the rash has healed. HIV, Lyme disease, and hepatitis C are other known triggers.

Key facts:

• The shingles vaccine significantly reduces the risk of postherpetic neuralgia
• Antiviral medicines work best when started early in a shingles episode
• Postherpetic neuralgia can last months or years without treatment
• Pain medicines specific to nerve pain are often needed for post-infection neuropathy

6. Chemotherapy and medications

Many cancer treatments — particularly platinum-based chemotherapy drugs like cisplatin and oxaliplatin — are well-known causes of peripheral neuropathy. Certain other medicines, including some antibiotics (metronidazole), anticonvulsants, and statins, can also cause nerve damage over time.

Key facts:

• Chemotherapy-induced neuropathy can develop during or after treatment
• Dose adjustment is sometimes possible to reduce severity
• Symptoms may improve slowly after treatment ends
• Specific nerve pain medicines can provide significant relief

7. Hereditary conditions

Some people are born with a genetic predisposition to nerve problems. Charcot-Marie-Tooth disease is the most common inherited neuropathy in the UK. It slowly affects the peripheral nerves, causing muscle weakness and sensory loss, particularly in the lower legs and feet.

Key facts:

• Symptoms usually begin in childhood or early adulthood
• There is no cure, but physiotherapy and orthotics significantly improve quality of life
• Genetic testing can confirm the diagnosis and help family members
• Pain management is an important part of long-term care

Symptoms of neuropathy

Neuropathy symptoms vary widely depending on the nerves affected. However, there are several warning signs that most people experience. Recognizing them early can make a significant difference to outcomes.

Sensory symptoms are the most common and include:

• Burning, stabbing, or shooting pain — often worse at night
• Tingling or "pins and needles," particularly in the hands and feet
• Numbness or reduced sensitivity to touch, temperature, or pain
• A sensation of wearing invisible gloves or socks
• Extreme sensitivity to touch — even light contact on the skin can cause pain (allodynia)

Motor symptoms occur when motor nerves are involved:

• Muscle weakness, particularly in the feet and hands
• Difficulty with balance and coordination
• Dropping things or tripping more frequently
• Muscle cramps or twitching

Autonomic symptoms develop when autonomic nerves are affected:

• Dizziness when standing up (postural hypotension)
• Bladder or bowel problems
• Excessive sweating or inability to sweat
• Heart rate irregularities

Treatment Options for Neuropathy

There is no single treatment that works for everyone. The best approach combines addressing the underlying cause with managing symptoms directly. Here is what current evidence and NHS guidance support.

1. Treating the underlying cause

This is always the priority. If the neuropathy is caused by diabetes, tighter blood sugar control can slow or stop further nerve damage. If it is caused by a B12 deficiency, supplementation can reverse symptoms. If it stems from alcohol use, reducing intake dramatically reduces progression. Treating the root cause first gives all other treatments a much better chance of working.

2. Prescription nerve pain medications

When pain is moderate to severe, prescription medicines are often necessary. Several classes of drugs are specifically effective for neuropathic pain:

• Pregabalin and gabapentin: anticonvulsants that calm overactive nerve signals. These are among the most commonly prescribed medicines for neuropathic pain in the UK and are effective for diabetic neuropathy, postherpetic neuralgia, and fibromyalgia-related nerve pain.
• Amitriptyline and duloxetine: low-dose antidepressants that alter how the brain processes pain signals. Duloxetine in particular is recommended by NICE for diabetic neuropathy.
• Tramadol: a stronger painkiller sometimes used for severe neuropathic pain when other options have not provided sufficient relief.
• Topical treatments: Lidocaine patches and capsaicin cream can reduce localized pain without systemic side effects.

3. Physiotherapy and Exercise

Regular exercise such as walking and low-impact activities. It improves circulation to the nerves and can reduce pain levels over time. Physiotherapy is particularly helpful when motor nerves are affected, improving strength, balance, and coordination.

4. Pain Management Techniques

Beyond medication, several approaches help people manage neuropathic pain day to day:

• TENS therapy: transcutaneous electrical nerve stimulation uses mild electrical pulses to interfere with pain signals
• Mindfulness and CBT: both have evidence for reducing the perceived intensity of chronic pain
• Acupuncture: available on the NHS in some areas and used as a complementary approach for nerve pain
