    Are There Risks?

    Yes. It could injure the nerve or nearby blood vessels, including your carotid artery and jugular vein. Plus there are risks associated with any surgical procedure, like infection, bleeding, or an allergic reaction to the anesthesia.

    Does It Work?

    VNS isn’t a cure. It’s rare for seizures to go away completely. But many people who have VNS notice that their seizures are less frequent and less severe.

    Are There Side Effects?

    The most common ones include hoarseness, coughing, tingling in the neck, and problems swallowing. These usually happen only when the nerve is being stimulated. These side effects generally are mild and tend to go away over time.
