I had it a few years ago. Scared the bejeepers outta me when my face drooped.
I thought I was having a stroke.
My doctor diagnosed me quickly and put me on a prednisone dose pack. The side effects from the meds were nearly worse than the Bells palsy, and can't be discussed in detail on a polite forum like this one.
I was in my late 40's when I had it.
Most of my facial function returned within 2 to 3 weeks. I still have some slight residual loss of function on the right side of my face, but it is very slight, and not apparent to the rest of the world.
Keep half-smiling and expect the best.
