Neuropathic Pain


What is neuropathic pain?

Neuropathic pain is a term to describe pain that arises from abnormalities of the nerve. Trauma, compression, infections, medical diseases and stroke can damage nerves. Some examples of neuropathic pain include slipped discs with sciatica, shingles, trigeminal neuralgia and diabetes-related peripheral nerve pain.

What is the treatment for neuropathic pain?

Besides treating the underlying problem, neuropathic pain should be managed early and aggressively. Neuropathic pain responds poorly to common painkillers such as paracetamol and anti-inflammatory medications. Anti-depressants, anti-convulsants as well as opioids are frequently used. Severe cases of neuropathic pain will benefit from spinal cord stimulation.

What is spinal cord stimulation?

Spinal cord stimulation uses implanted electric wires (or leads) placed onto the spinal cord to block pain signals. A battery – known as an implantable pulse generator - generates tiny electric current to stimulate the spinal cord. When the stimulator is switched on, the painful part of the body is replaced with a comfortable tingling sensation.

Diabetic Neuropathy


What is diabetic neuropathy?

Diabetic neuropathy is due to nerve damage from diabetes, especially poorly controlled diabetes with high blood sugar level. Nerves in the hands and feet are most commonly affected – a term called diabetic peripheral neuropathic pain (DPNP).

What are the symptoms of DPNP?

The hands and feet may experience sharp pricking pain, burning or cold sensation, numbness, tingling, hypersensitivity to touch or temperature changes. Symptoms may be worse at night. Walking barefooted, wearing socks or shoes may be unbearable.

How is DPNP treated?

Treatment is focused on relieving pain and slowing the progression of the disease through good blood sugar control.

Common pain medications do not work for neuropathic pain. Antidepressants, anticonvulsants or even opioids are required.

Spinal cord stimulation is a possible treatment for DPNP that is severe and persistent.

Frequently Asked Questions (FAQs)

About Trigeminal Neuralgia

What causes facial pain?

Facial pain, particularly that associated with trigeminal neuralgia, is most commonly caused by a malfunction in the trigeminal nerve, which is the primary nerve responsible for sensations in the face. While the exact cause may vary, often it can be attributed to a blood vessel pressing against the nerve, leading to severe, sharp facial pain. Rarely, other causes such as a tumour or nerve damage due to disease can also contribute to facial pain. Treatment is often sought for this condition.

What are the common symptoms of trigeminal neuralgia?

Trigeminal neuralgia presents with several characteristic symptoms. The most prominent one is a sudden, severe, sharp or stabbing facial pain. The pain often occurs in bouts and may be triggered by everyday activities like talking, eating, brushing teeth, or even a gentle breeze. The attacks may last from a few seconds to a few minutes, and they can occur repeatedly throughout the day. In some cases, patients may also experience a burning sensation or numbness in the face. Treatment is usually required to combat the intense discomfort associated with this condition.

What is the treatment for trigeminal neuralgia?

Treatment for trigeminal neuralgia aims to relieve the symptoms and manage the pain. The standard first-line treatment is medication management, including drugs such as carbamazepine, gabapentin, or pregabalin. These medications help in reducing the nerve’s response, thus relieving pain.

However, if medication fails to provide relief or causes significant side effects, other treatments such as Radiofrequency Ablation may be considered. This treatment involves inserting a special needle into the trigeminal ganglion and using radiofrequency energy to create heat, which destroys the painful division of the trigeminal nerve.

For cases where trigeminal neuralgia is caused by a blood vessel or tumour pressing on the nerve, referral to a neurosurgeon is needed. They may recommend surgical intervention to remove the pressure on the nerve. The choice of treatment depends on the individual’s health, severity of symptoms, and their response to medication. Always consult with a specialist for the best-suited treatment for your condition.
