I had an MRA and it showed normal brain blood vessels. Because I have sensory-motor neuropathy, my neurologist feels the TN is from the same cause as the problems with my legs.

Today and tonight I have had vision changes with difficulty reading and my face is swollen and tender. Won't be able to sleep on the left side.

I am taking 400mg tegretol 2x a day and it keeps the pain at bay. Hopefully the next round of tests will determine the cause of the neuropathy and they can start some kind of treatment. My hope is that it will help the TN too.
