Hello Sally,
The advice you've been given on here is quite sound. MS can not be picked up on a regualr radiograph. It does sound like they were describing some type of "Degenerative Disc Disease" in the findings which is not unusual. Not to become alarmed. If I recall, weren't you set up for some tests this week? I don't recall if an MRI was ordered or not, but an MRI and/or Lumbar Puncture would make the diagnosis definitive. You continue to be in my thoughts as always.

All the best,
Chris
