Pain arising from structures supplied by the phrenic nerve is often "referred" to other somatic regions served by spinal nerves C3-C5. 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.
Kehr's sign is a classic example of referred pain: irritation of the diaphragm is signaled by the phrenic nerve as pain in the area above the collarbone. This is because the supraclavicular nerves have the same cervical nerves origin as the phrenic nerve, C3, C4, and C5. [citation needed]
Uncle Carl, a Marine, had a grip that would crush brick and a stare that would melt pig iron, and never mind this foolishness about an irritated vagus nerve or an overactivated phrenic nerve ...
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
A doctor can help rule out more serious causes, and identify whether further treatment is necessary. Getting rid of intractable hiccups often involves treating the underlying cause, the experts note.

Numerous medical remedies exist but no particular treatment is known to be especially effective, generally because of a lack of high-quality evidence. [23] [24] A vagus nerve stimulator has been used with an intractable case of hiccups. "It sends rhythmic bursts of electricity to the brain by way of the vagus nerve, which
Other areas of the nervous system that have been affected are the phrenic nerves and the recurrent laryngeal nerve. As the nerves lose function, the muscles associated with those nerves begin to atrophy. In brachial plexus degeneration, atrophy may occur in the deltoid muscles. In phrenic nerve degeneration, the diaphragm may be affected.
