The causes of tingling in the right arm can include compression of the veins in the arm due to pressure placed on the arm from outside of the body. For example, if you fall asleep on your right arm, you can then feel tingling in the arm once the pressure is removed. Other causes of this tingling can include heart attack, stroke, diabetes, vitamin deficiencies, nerve palsy, spine or back injuries, shoulder injuries, and brain damage.
