memory problems, insomnia symptoms, chronic pain, and twitchy feelings in muscles are actually very characteristic of narcolepsy
with cataplexy. In fact, often times, it's not "Bells Palsy," but cataplexy. Viruses and some vaccines (namely the H1N1) can actually precipitate this, but it can happen seemingly in random fashion, too.
Common misdiagnoses are depression, epilepsy, and migraines.
It doesn't look the way you think it looks.
