[QUOTE=Comeonthen;1218239]Thanks for your reply.
I have severe mobility and neuropathic pain problems in legs. After MRI and an operation 10 years ago bone spurs and "spinal epidural lipomatosis" (SEL) were both identified as needing attention. The white spots could be an example of SEL though of course I am not qualified in to pronounce.

SEL is an accumulation of fat globules within the spinal cavity which, if they impinge on the spinal cord itself can cause similar problems as bone spurs. If you use that term in a web search engine you can find out about the causes of SEL and there are a few examples of MRI images of them.

Hope this is helpful.
