When I use my mobile while in sleeping position with one hand raised holding mobile for 10-15 minutes I get numbness in the hand in which I am holding the mobile. Also if I keep my hands raised up for some time then I feel numbness in hand or fingers. Some times when I am sleeping at night & if I keep my hand upwards above the head then also I feel numbness in both hands & is not able to move my hand for few minutes till blood circulation flows. Facing this issue for almost two years. Is this normal? Could it be  blood circulation  issue? Is it also related to volume of blood in body? What could be the reason for such issue? How do I cure it any exercises recommended. Rest my CBC report is normal, no dibetis, no major health issue
