[QUOTE="nephron, post: 706239, member: 23759"] Sounds very 'disky' ;) ; typically starts with an unusually minor event, and is exaccerbated by similar movements. Relatively 'stable' or not bothersome until another freak movement causes it hurt like hell. Sharp, local pain? Lumbar or Thoracic? Either case, they're really not that dangerous--just a pain in the butt. I wish I could draw you a picture, but discs reside b/t vertebral bodies. Consider that just posterior to the vertebra (and disc) is the spinal cord itself, which is surrounded by these things laminae and pedicles Every level, 2 nerve roots exit at either side b/t the laminae (which has formed a nerve exit opening). This nerve contains all connections needed to provide sensory and motor function to its distribution. Things are cozy until the nucleus pulposus decides to herniate out posteriorly from its lateral side to back, placing the point of maximum impact at the nerve trying to exit the neural foramina. As it herniates, it causes the fibrous portion of the disc to push hardly on the nerve root. Depending on the severity, it can just be severe, intermittent pain, but might be as bad as to compromise motor function in that 'myotome'. Those people need surgery yesterday. The best treatment (IF you have disc disease) for a case like yours would be steroid/marcaine injections directed right to the nerve outlet. There's no way of telling that that's what you've got (without looking you over, etc.), but a noncontrast MRI would be the best test (you did right). Contrast is reserved for finding epidural abscess, malignancy, etc. [/QUOTE]
