Continuous upset stomach, fast heart beat, feel disoriented and anxious, feel like everything is moving but i'm sitting still. what is going on?

Not sure...: Your symptoms could be dehydration, side effects from pain medication, allergic reaction to medication (I say those 2 b/c u may be on antibiotic n pain med if just did tooth extraction), inner ear problem, anxiety, or some combination of all. Do you have a fever? Can you still eat? Does it change sitting/laying down? Regardless, u need to be seen in person by someone. So get a ride to your doctor!
