Continuing my previous post on b12 deficiency, I always had great communication skills and vocabulary but lately I am having a terrible time remembering words and am mixing up grammar (like using singular with does etc). There's no trend whatsoever and sometimes I forget common words like "decorum" and "ignorant" too. I re-read my sentences multiple times when i type to ensure there are no grammatical or spelling errors. This has reached a state where I have become completely paranoid. Also sometimes I have pronounciation issues with words which I have been using since childhood. Do you think these are classical symptoms of b12 deficiency or there might be something more sinister at work here? I am thinking of getting b12 shots from my GP but if he goes for a b12 blood test, seeing the results, he will immediately ask me to get lost. How do I convince him to hear me out?
