The most common cause of long-term hiccups is damage to or irritation of the vagus nerves or phrenic nerves, which serve the diaphragm muscle.Factors that may cause damage or irritation to these nerves include: 1  A hair or something else in your ear touching your eardrum. 2  A tumor, cyst or goiter in your neck.
Hiccups are caused by involuntary contractions of your diaphragm â the muscle that separates your chest from your abdomen and plays an important role in breathing. This involuntary contraction causes your vocal cords to close very briefly, which produces the characteristic sound of a hiccup.
