The other day I parked my car and started to walk the block to my office. All of a sudden I felt a hot burst of electricity run through my body, in my chest area. It's happened before - not too often, but enough for me to notice. Does anyone get that symptom and do you know what it is and what causes it? My heart is fine. It makes me very anxious and creeps me out. What in heaven could that be? Thanks! Annette2 P.S. - HAPPY BELATED 4TH OF JULY!!!! We're in the Greatest country in the world!!!!
