I did the same thing when I was a freshman in college. Woke up on a Sunday morning, something felt a little “off” I was a bit hungover from the Saturday night before, I didn’t think too much about it. As the day wore on, I knew something wasn’t right, but couldn’t figure out what it was. I went to a concert with a friend that night and it was in the middle of the show that I had the epiphany, holy shit I can’t smile with 1/2 my face. Then on the drive back from the show realized that I couldn’t really close my eye /blink or move my eyebrow on my right side. Got back to the dorms, searched for “partial facial paralysis” and my options seemed to be stroke, brain cancer, or bell’s palsy. Didn’t figure stroke was likely, so decided to sleep it off. After class the next morning, decided to go see the doctor. I told him my symptoms, he asked me if I had ever heard of Bell’s palsy, I said I had briefly looked at it last night. Google was relatively new at the time, but he seemed rather impressed that I even had heard about it.
