18 year old female. symptoms are loss of consciousness, body numbness(entire body), blurry vision, shortness of breath, chest/rib pain, pounding heart beat, black outs. my doctors did an ekg and the results were normal and then they gave me a 48 hour heart monitor and they said my heartbeat was fast. when i got a call back they said i was having a panic attack, im wondering if these symptoms could be a result of something else. ive never heard of a panic attack lasting longee than an hour and three of my symptoms last the entire day and have for weeks.
