E.G.
Ugh! I feel for you! Every case is different, so I would continue to take the advice to explore all options, but I also wanted to sympathize as someone who's also had Bell's Palsy.
I got it on one side of my face near the end of my first pregnancy. I was also panicky, went to the ER, who took one look at me and knew what it was. It didn't START to get better until 6 weeks later (ugh) but I remember once I started to feel "tingly" on the palsy side, everything came back within a week or so, and soon after you couldn't tell it ever happened. It is so scary to have - you think it's never going to go away, but it does. I also took steroids that had no effect.
While I had the Bell's Palsy, I kept in touch with my cousin, a speech therapist, who told me about a therapy called e-stim (another poster also mentioned this) which could help in the rare case that recovery is even slower than mine.
So, I feel for you!!! Here's to a speedy recovery.
