How is a Herniated Disc Diagnosed
A herniated disc should be evaluated by a spine specialist who will perform a thorough clinical evaluation, which will include a history and physical examination. Careful assessment for any weakness, loss of sensation, or abnormal reflexes will be done at the time of your exam. Furthermore, if there are any problems with bowel or bladder function, this is considered a surgical emergency. An MRI confirms a diagnosis of a herniated disc. An MRI is not indicated for approximately six weeks after the onset of symptoms, unless there are other warning signs that are evident at the time of the history and physical examination. An MRI is the preferred diagnostic study when evaluating for a herniated disc. However, some patients are not able to undergo an MRI, such as those patients with a pacemaker, and a CT scan can be used. In addition, electrical nerve studies called EMG’s may be performed to look for signs of nerve damage.
