I just got back from having a physical, I picked up some french fries to eat for lunch, walk to lunch room from my car, once I got back to work, and now my heart is racing fast. My chest feels in middle by heart wierd. My throat is a bit sensitive. I feel a little week, and maybe faint but I am up right sitting in my wrk chair. I am startign to get a bit of a headache, but my heart is racing...
