Schools Financial Credit Union routing numbers are also known as as ABA numbers, routing transit numbers (RTN), or check routing numbers.
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 due to the involuntary contraction of the diaphragm muscle. This causes you to inhale suddenly, followed by a reflex shutting of the epiglottis, which makes the hic sound. Hiccups are stopped by stimulating the vagus nerve to the diaphragm, such as by drinking water upside down.
