Neuropathic pain: It is a nervous system disorder caused due to damaged sensory nerves. It is caused by chronic progressive nerve disease, infection, or injury. The pain could be intermittent or continuous, which is felt as prickling, stabbing, tingling or burning sensation. A feeling of numbness and loss of sensations is also common with neuropathic pain. Symptoms include spontaneous, untriggered pain, unpleasant feeling, shooting, burning or stabbing pain, difficulty resting or sleeping, and evoked pain (pain caused by events that are usually not painful).
