Nerve pain has become something of a catch phrase on TV ads for one medication or another. Sometimes called neuralgia or neuropathic pain, it occurs when a health condition directly affects the nerves that carry pain sensation and is typically different to other types of mechanical or inflammatory pain. It may occur following a disease or injury, for instance 'shingles' often results in what is known as 'post herpetic pain' because it is caused by the varicella-zoster virus lodging in a nerve root. The damage might cause the nerves to misfire and send pain signals to the brain that may feel like burning, shooting or stabbing pains. Nerve entrapment in the case of a disc protrusion for example, may damage the nerve and cause neuropathic type pain. Treating the source of this pain is usually the first step, and it is in this that Physiotherapy can sometimes be highly effective.
