**NEURALGIA AND NEURITIS**

**(Radiculitis)**

Neuralgia is a sharp, stabbing pain along the path of a nerve,
noninflammatory. Neuritis is an inflammation of a nerve, which may be
characterized by neuralgia, loss of sensation, restriction of motion,
and occasionally muscular wasting. It may be localized and affect a
single nerve trunk or generalized and involve many nerves. For purposes
of rating no distinction is made between the two conditions.

Frequent causes are injury, exposure to cold, pressure, and focal
infections as from the teeth and tonsils. Vitamin deficiencies,
syphilis, chronic alcoholism, lead, arsenic and other poisons may cause
persistent and disabling neuralgia and neuritis. With involvement of
left arm, shoulder or chest at ages over 40, consider the possibility of
angina pectoris.

**Underwriting Requirements**

An APS (VA Form 29-8158) is required if not adequately described.

**NEUROFIBROMATOSIS**

**(Neurofibroma, Neuroma and Neurilemmoma, Neurinoma)**

A neurofibroma is a benign tumor of nerve tissue occurring most commonly
in the skin. Neurofibromatosis is a syndrome characterized by multiple
nerve tumors and characteristic skin changes, and, in a small percentage
of cases, by mental deficiency, seizures, musculoskeletal abnormalities,
hypertension or pheochromocytoma.

**Underwriting Requirements**

An APS (VA Form 29-8158) is required. Ratings will vary widely from no
debits to rejection in unusually complicated cases.

**NOSE BLEED**

Bleeding from the nose (epistaxis) is most commonly due to injury but
may accompany ulceration, inflammation, or tumor formation in the nasal
passages. It is sometimes a symptom of acute contagious disease, such as
typhoid fever, influenza, measles, and undulant fever. Severe, prolonged
or recurrent attacks may be due to various anemias and other blood
disorders. At older ages, hypertension is a common cause.

**Underwriting Requirements**

Isolated attacks, due to trauma or varicosity of nasal mucosa may be
disregarded. For others, obtain an APS (VA Form 29-8158).
