B12 neuropathy symptoms/criteria

Posted By Jen Schiller on March 18, 1998 at 20:09:39:









What are the specific symptoms of PN caused by Vitamin B12 deficiency?  How long is the usual course of these symptoms?  Is tingling and then numbness of the lower back a common symptom?  Are peripheral nerves also affected?  Can B12 deficiency cause weakness and, within days, paralysis? Lastly, is it possible to have a severe enough B12 deficiency to cause PN, if you had gastric surgery less than a year prior to the appearance of the first symptoms?  I had preserved reflexes in my legs and a positive Babinski's when paralyzed, so that seems to rule out GBS.  Neurologist says it is not possible to get PN from B12 deficiency, even when I had pernicious anemia, etc. because it takes YEARS for PN to develop. Can't find the symptoms and criteria for B12 deficiency/PN anywhere I have looked.  Would appreciate this knowledge if you can share.  Tahnks so much for this great BBS.
