Have trigeminal neuralgia, dr recommend blood test for b12 level is this necessary?
A doctor has provided 1 answer
Yes: Low B12 levels can absolutely make neuralgias worse; if corrected, they can improve neuralgias. It is a "rule-out" test, to try and determine the etiology of your trigeminal neuralgia.
