Why do some neurologists say the spine can repair itself?

"The cervical spine is where the spinal cord lives," said Volker K.H. Sonntag, MD, a member of the American Association of Neurological Surgeons Board of Directors and a neurosurgeon practicing in Arizona. "The spinal cord is the most delicate tissue in the entire body. Even minor damage to the spinal cord cannot be repaired. Unlike low back pain, in which waiting to seek treatment may prolong the pain but usually doesn't cause any further damage, untreated spinal cord compression can lead to irreversible damage."

I had a disc, dislodged and bruising my spinal cord, for well over a year. (I'd say closer to 2, given an episode with the chiropractor that I recall to this day was a bit painful...)

I won't say more for now except I'm scheduled for another visit in about a month...
