What Causes Sudden Nausea, Hot Flashes And Dizziness?

Yesterday morning i was doing my regular routine and all of a sudden, became nauseous, sweaty hot, dizzy then fainted. I came to after needing help up off floor. Didn't faint again, but the rest of the day n night, and today, my legs and knees are week and hurt. Ive felt dizzy a little a few times today, but nothing like yesterday. Is the legs/knee thing from falling or should i go to ER just to be safe?

Sudden onset feeling of nausea dizziness fainting episode should be taken seriously . This may be because of some rhythm disturbance in your heart or may be manifestation of decrease blood supply to your heart or may be because of some disturbance in blood supply to your brain.you need to get your blood pressure sugar and ECG monitoring done. if needed brain imaging could be done.in the mean time you have to take care of yourself while standing from sitting and supine position .stand slowly and with support . Maintain your hydration status good.
