Have you been seen by a good neuro specializing in peripheral Neuropathy? I'm guessing that you see one for the epilepsy. But have you seen one specifically for the neuropathy symptoms?
Also take a look at
www.lizajane.org.
I think I remember Reynauds has peripheral neuropathy as one of it's symptoms. So have you been seen by a rheumatologists?
Also, with the migraines, they could be caused by structural problems in your neck. This is something that I had and a ruptured disk and subsequent fusion helped them a lot. So an evaluation by a rheumatologist to see if there is degeneration from bone problems might be in order. I believe Glenn has posted that perpheral neuropathy can be caused by problems in the upper spine.
Just some ideas I'm throwing at you.
