Hello. I am unable to move / raise my fingers on my right-hand when I bend the wrist upward. When the wrist is not raised, I can move my fingers. There is no pain at all, but there is numbness/tingling on the left-half of the hand from the middle finger to the thumb. The symptoms started overnight out of nowhere. I initially thought I slept in a poor position in which the blood flow to the hand/wrist/forearm was impeded. The feeling is similar to when an arm or leg falls asleep plus the immobility. Thanks for your help!
