Hi, am 28yrs old. feeling numbness in hand fingers and toes some times.mostly while sleeping n early morning before wakeup.what is the cause?

Many causes of numb: There are many possible causes of symptoms like yours. If the hands and the feet are affected often, a cause such as vitamin B12 deficiency could be considered. Are you a vegetarian? Vegetarians often do not consume enough vitamin B12. Other causes could be diabetes mellitus or carpal tunnel syndrome, at least for the hands.
