If you have hiccups for over a day do to go the doctor?

Hiccups that persist for more than 48 hours are considered persistent and should be evaluated by a doctor to determine the underlying cause and recommend appropriate treatment. Prolonged hiccups can be a sign of an underlying medical condition or irritation of the phrenic nerve, which controls the diaphragm muscle that causes the hiccups. Seeking medical attention is advisable if the hiccups are accompanied by other symptoms, such as fever, chest pain, abdominal pain, nausea, or vomiting.
