Why does my hand hurt?
All of a sudden, the lunate bone area (left side near the wrist) of my left hand started to hurt. Whenever I move my hand upwards the top hurts. I am not a left, and do not use the muscles of my left hand for much but typing, holding a trumpet, and playing the flute. Please help me understand why my hand hurts and how I can get it to stop hurting (besides pain killers)
