Hi Dr Corenman
Thank you for your quick and informative reply.
The spasm can be quite painful when it lingers.
My impression over the years is that the muscles seem to have a few chronically active fibers, the tension of which extends from the sacrum to the skull. Stretching produces a burning sensation along the muscle and they are thermally warm in specific areas. What I am wondering is if lumbar foraminal stenosis can result in chronic low level paraspinal muscle activation by compression of the portion of the exiting nerve that becomes the dorsal rami rather than pain avoidance. Probably a moot point but lumbar and cervical disc herniations seem to co-occur rather frequently. I am hesitant to undergo surgery for a bit o sciatica, but if the muscle spasms can be eliminated I would a sign the waiver tomorrow.
Thank you for the wonderful website.
