No, cause of Bell's never really identified, not sure it ever is. I went on acyclovair and steroids and eventually faded but it may have just been time.
Had no virus (cold symptoms) at the time.

As I'm typing this (night) I am very fatigued and lost my appetite, feeling very down. Seems to happen at night. I took 100mg gabapentin last night, might again but didn't think there was any effect.

Thanks for all your postings, helps to know there are others out there for sure.
