so I walked into work today feeling fine. I got me a cheese cube to snack on cuz I felt a little hungry. while waiting to clock in I was talking to a coworker and she said all of a sudden what I was saying didn't make sense and I was looking flush. I sat down because I got dizzy and really hot all of a sudden. then I started puking so I went home. slept about 2 hours and now I feel fine again besides a small headache. should I be worried enough to call my Dr?
