Too many causes: Vascular cause and periferial nerve cause. You listed cold sensitivity. Do you have more numbness in cold wheather? If you do it could be raynaud's phenomenon. See your doctor. Both arms? Do you have a glass (cold) on your desk top? Do you have carpal tunnel symptoms? See your doctor.
