Pain associated with the sciatic nerve usually originates higher along the spinal cord when nerve roots become compressed or damaged from narrowing of the vertebral column or from a slipped disk. Several different tests can be performed to find the cause of sciatic nerve dysfunction. Have you had an MRI of the spine taken recently?

Yes. Since the surgery (4.30.0, I have had 1 mri, 1 emg, 1 discogram, and 1 cat scan. I go to the doctor tomorrow to discuss the results from the discogram and the cat scan.

The emg showed significant nerve damage. The last mri showed a bulging disc. I am not in near the pain I was in prior to the discectomy. But, I am still in minor pain and have very limited movements.

The doctor said that according to the mri, it is not worth doing a second surgery at this point because it will cause more damage than good (twice as much scar tissue, inciscions, etc.). After he looks at the discogram, he'll be able to give me more info.

But I'm wondering if I don't do surgery now, am I just a walking time bomb? Waiting for the bulging disc to do more damage?

Invasive surgery is the LAST OPTION that you'll want to consider in any condition. Has you doctor recommended physical or physiological therapy at this point?
