Glove Anesthesia is a psychosomatic disorder in which you have no feeling or that "pins and needles" feeling. Glove Anesthesia affects only the hands. The fingertips to the start of your wrist loses feeling.
So how does this connect to psychology? The nerves that give sensations to your hands are the same ones that go to your lower arms. Physically, the hand cannot be numb without the lower arm being numb. You might be thinking "what about a pinched nerve?" A pinched nerve would be a physical condition that could explain the numbness. In this case, there's a clear physical cause of the pain.
