What Causes Pain?
One possibility for pain is disk involvement. Pain may occur when a disk becomes inflamed, herniated (bulging), or ruptured. The mechanism can be due to an acute injury like a car accident or fall, or repetitive micro-trauma (long term wear and tear). In both cases, muscle spasms can occur, potentially causing severe pain.
