MS lesions and epidural blocks

Hello!

I recently have had month-long episodes of bilateral heat-sensitive femoral neuropathy, accompanied by extreme fatigue, bowel and bladder problems and painful eye sensitivity to light. My doc is sending me to a neurologist because he suspects MS. My question is this. I also had a painful nodule around the L3-L4 area of my spine, and the only injury in that area was an epidural block 7 years ago. Could that block have started a spinal lesion that would produce this neuropathy?

Thanks very much!
