It. neitralgia,< NL. neuralgia, < Or. vevpov, nerve, 
+ 4A>of, pain.] A pain, corresponding fre- 
quently to the distribution of some one nerve, 
which is not due immediately and simply to 
excessive stimulation of the nerve or nerves 
involved by some gross or extra-nervous lesion, 
but to a nutritive or other molecular change in 
the nerves themselves or their central connec- 
tions. The pain Is usually paroxysmal, varying in in- 
tensity, and described as shooting, stabbing, boring, burn- 
ing, or deep-seated. Neuralgia is largely confined to 
adult life, Is more frequent in women than In men, and 
is especially apt to occur In neuropathic individuals. It 
is Induced by cohl, exhaustion (from overwork, worry, 
over-lactation, mental shock, lack of food and rest), ane- 
mia, malaria, ali-nhol. Irad, and glycohemla. In addition to
