My first symptoms were strange tastes, then facial numbness - by the time I finally got my first appointment with a neurologist, I had tightness, mild twitches, and tingling + my left eye was looking different and didn't close with a good seal. I had very dry eyes and noticed that I couldn't feel eye drops going in my left eye either. A couple weeks later I had an MRI and learned I had a 3.1 cm tumor (mostly removed in June of this year). The neurologist said she was expecting they would find a tumor, but not so large - I already had hearing impairment so I didn't realize it was getting worse, and adjusted to the balance quite easily.
I've since been told that it is uncommon to have issues with facial nerve prior to diagnosis & treatment - much more common for balance and hearing issues to be the early symptoms. From looking around the forums here, I think we have some good company - the promising news is that facial nerves can recover (shame the hearing doesn't).
A couple weeks ago, I felt eye drops - not every time but every once in a while. I guess the sensations come back like a light bulb flickering rather than returning all at once. I hope your outlook is promising - you appear to be taking the news well and it seems like attitude is an important factor for how well you feel about your treatment choices and recovery.
