Vasovagal reaction
A vasovagal reaction (also called vasovagal syncope) is sudden dizziness or fainting that can be triggered by pain, fright, or trauma. The person may sweat, feel lightheaded, nauseated, or tingly, and may pass out if the reaction continues.
A vasovagal reaction can happen without serious cause. However, vasovagal reactions may be caused by heart problems, epilepsy, or other conditions that require treatment.
A vasovagal reaction can usually be relieved by lying down with the legs elevated. However, treatment is necessary if a medical condition is causing the vasovagal reaction.
