Hello I had a one second flutter in the center of my chest and felt a little dizzy had a cold sweat...then it went away as fast as it came....then every hour or so since I'm getting little feelings of the same but they go away quickly....this is been happening for the last 4 hours or so.........never had this before......had a huge mean of shrimp and crab.....about 3-4lbs worth....could that have anything to do with it?
