An accumulation of fatty tissue compressing the spinal nerve, most common cause said to be long term use of steroids though also associated with obesity. Neither cause applies to me unless a single cortisone injection given many moons before the symptoms of neuropathic pain and neurological deficit affecting my mobility became apparent, so I guess that the 'autoimmune' catch-all term applies.

Any experience of similar condition would be most welcome.
