Get seen : When you passed out most likely Vaso Vagal syncope -brief loss of consciousness due to a neurologically induced drop in blood pressure.it is divided into three types: vasovagal, situational, and carotid sinus.Vasovagal syncope is typically triggered by seeing blood, pain, emotional stress, or prolonged standing.It is is often triggered by urination, swallowing, or coughing.Need to see why a fever.
