Hello KY!
I have the same symptoms during the last two weeks. I have twitches in my middle and index finger. Also I notice many sounds when moving my head from left to right and I have neck pain. I have an appointment with the neurologist in two weeks but I think perhaps it could be a brachial plexus injury due to hundreds of hours of poor posture in front of my computer.
Sorry for my English, I´m from Spain!
