Neuropathic pain is a type of chronic pain that results from damage or disease affecting the somatosensory nervous system. It is caused by damage or dysfunction of the nerves that transmit signals between the brain and spinal cord and the rest of the body. Neuropathic pain is chronic and is often described as burning, stabbing, tingling or numbness. This pain may be constant or intermittent and may be accompanied by sensitivity to touch or temperature changes. Other symptoms can include muscle weakness, loss of sensation, and changes in skin color or temperature in the affected area. These symptoms can vary depending on the cause and location of the nerve damage. It can be caused by a variety of conditions, including diabetes, cancer, shingles, spinal cord injuries and nerve damage due to surgery or trauma. It can also be caused by certain medications or toxins.
