Patients with facial neuritis generally do not experience vomiting. The main symptoms in patients are paralysis of the facial expression muscles around the eyes and mouth, which may present with the disappearance or lightening of the wrinkles on the affected side of the forehead, enlarged eye slits, incomplete eyelid closure, and exposure of the white sclera when attempting to close the eyes. Additionally, flattening of the nasolabial fold may occur, as well as reduced or lost taste sensation in the anterior two-thirds of the tongue. Patients may have symptoms such as a crooked mouth when whistling, air escape when puffing cheeks, and food retention on the affected side during meals, which increases the risk of oral infections and conjunctivitis. If vomiting occurs, other causes should be actively considered, such as the possibility of high blood pressure or electrolyte imbalance like hyponatremia. Dietary indiscretion could also be a cause, necessitating a comprehensive analysis.
