Hello Cheryl,
There are many of us on the board who have or had sciatic pain, and many who have had surgery. We all understand your pain and the frustration you have when your activities are limited by your back issues and pain.
First, are you seeing a fellowship-trained spinal specialist? This is either an orthopedic or neuro surgeon who has additional training in the back and spine and only works on those cases. I feel like surgery is being recommended to you awfully early in the process. Usually, except in emergencies, surgery is offered as a LAST resort, after all other options have been tried and considered. Surgery is not a guarantee that you will be painfree. It will not return you to the way you were prior to the herniation.
While the disc pressing on the nerve root can cause permanent nerve damage, it would not cause you to be paralyzed as the spinal cord stops above the level where you have the herniation. It could result in loss of feeling, nurabness or foot drop. Many people live with nerve pain caused by nerve compression for many years before surgery becomes necessary. In almost all cases, this type of spinal surgery is considered elective surgery.
There is a possibility that the herniation could heal itself and that the sciatic pain would resolve. This might involve physical therapy and rest for a bit...and then very gradually resuming your activities. My husband was able to do this 15 years ago and he has been fine ever since. He does his back exercises faithfully every day and is careful how he uses his body...but he otherwise leaRAB a normal life.
My suggestion to you would be to get at least another opinion, preferably several more before letting anyone talk you into surgery. And to proceed cautiously and conservatively. Just remeraber, once surgery is undertaken, it is forever!!
