A pinched nerve is an injury to a nerve or group of nerves resulting from compression, entrapment or stretching. Numbness, tingling, burning or pain can result. In some cases, muscle weakness can also occur. Symptoms of a pinched nerve may develop gradually or can come on suddenly. Nerves can be compressed as they leave the spine; when they pass over bony prominences, through muscles, or under ligaments; or as a result of trauma.
