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.

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.

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.
