A 49-year-old female asked:
What can cause light headedness, tingling in arms and hands, like needles pricking your skin, heart fluttering, and anxiousness?

Hyperventilation: When you are anxious or stressed for some reasons you hyperventilate and your heart can flutter. During hyperventilation your blood chemistry changes in a negative way . You exhale to much co2 and your blood pco2 drops and this in turn decreases ionized calcium in the blood causing tingling , Decreased blood pco2 can give you light headedness. Breathing to a paper bag helps when under stress.
