I've been experiencing something strange with my hands. My right hand had some twitching, very slightly. I can see it twitching and my right thumb felt like it wanted to be stiff and touch my index finger. My left hand seemed to to feels a little numb and tingley. I've noticed that these type of things where my hands go tingley primarily happens at night or when I am in bed. It does not happen during the day or when I work. What could be causing this? I was told before that I might have Carpal Tunnel Syndrome, but I am not sure if this is what I have.
