I have been diagnosed with several t-spine herniations and am facing possible surgery. The worst of them are in the area of T8-9 and T9-10 and are compressing my spinal cord. For the past several weeks I've had numbness, tingling, and electrical shock sensations down both legs, in addition to my other symptoms. Since last night, I've had this burning pain down the back of my left leg and it's extremely uncomfortable. However, I thought sciatica originates from the lumbar spine? Is it possible this is related to the herniations in my t-spine, or does it sound like there may be issues with my lumbar spine as well? I've had an MRI and a CT myelogram, both of which were only of the t-spine. What do you think?
