Hi i just wanted to let you know i get this too. Not during the day though, but i waken up with them numb. I really dont know what causes this and the neuro i saw said... anxiety!!! Can you believe that??? When do your hands go numb? Are they totally numb? Have you saw your doc about it yet? Im sorry i dont know the answers, maybe someone else here can help but i just wanted to let you know your not on your own with this problem.
