lilyjames,YES, this is very common with BFS. I spoke to my neuro about it. Mine do the same. They are not concerned about numbness in the hands upon awakening AT ALL. For me, if I sleep with my hands resting on my chest, I will wake up with my thumb, index, and middle fingers numb (carpel tunnel). If I sleep on my side, I will wake up with my ring and pinky fingers numb (cubital tunnel). Our nerves are very easily irritated and sleeping with our arms in the same position for an extended period (even an hour or less) can cause this numbness. Its very common with BFS.-Matt
