Neuropathic pain is pain caused by diseases or injuries that affect your sensory system. Neuropathic pain is often described as “pins and needles,” burning or stabbing. It may be associated with abnormal or odd sensations and sometimes even normal non-painful sensations may be perceived as painful. Up to 10% of the US population may be affected, with over half having severe pain. Neuropathic pain may result from disorders of the peripheral nervous system or the central nervous system (brain and spinal cord). The most common type of neuropathic pain is painful diabetic neuropathy. Other common causes are chemotherapy and spinal root injury due to disc disease or spinal stenosis. In many people, the cause of the neuropathic pain is unknown, in which case it is called idiopathic neuropathy.
