does the entire hand go numb on you or 'only' certain fingers involved? do you feel any different sensations in any specific fingers or any stronger feelings than in others? is this only when you are waking up or sleeping or does this actually kind of come and go thru out the day? any neck pain at all? any real pain anywhere else? and knowing about ANY level of injury to anywhere either way before this started or recently would help to know too.
sorry for all the questions but they are needed to just better define this for you. 'numbness" is usually from only two possible sources, either a nerve/spinal type of issue or a vascular type of flow issue. FB
