    For example, a subphrenic abscess beneath the right diaphragm might cause a patient to feel pain in the right shoulder. Irritation of the phrenic nerve (or the tissues it supplies) leads to the hiccup reflex. A hiccup is a spasmodic contraction of the diaphragm, which pulls air against the closed folds of the larynx.
