question: When I get extremely upset, which is not often, I experience a tingling sensation on the back of my scull. Recently it happened but this time I felt it all over my whole body. Its not painful it just feels like the sensation you might feel if your foot falls asleep. It goes away when I calm down. What could be causing this? Am I having a panic or anxiety attack? Should I see my doctor and if so will he be able to find out whats wrong if it is in fact a physiological condition? I have an iron defficiency, but im otherwise in good health.
