A member asked:

Is it possible to have left sided disc herniation @ c5-6 with nerve impingement and have pain in the right arm from same?

Yes : I have had a few occasions to operate on patients with this problem with success. The problem is more convincing insurers to allow it than anything else. My theory is that pressure from the disk pushes the nerves against the bone on the other side thus creating opposite symptoms. I have seen this in both lumbar and cervical spines.

It is possible: It does happen, especially if it's a sizable disc (usually soft in consistency), which could exert a mass effect pushing the thecal sac containing the spinal cord towards the other side, which then results in the nerve root on the other side being pushed up against a "less soft" bone on the other side -- hence one can have pain on both sides, on side of herniated disc, or on the contralateral side.
