Your neurologist said it was nothing in June and didn't want to do any more tests so it seems like not a problem. i have an itching or biting thing that comes all day long sometimes sharp but the neuro guy told me it was just one of those things that you have to live with, so yours is likely the same thing. Same with your fear that you could feel your pulse that you mentioned on another thread, so i guess you must be an anxious person about this kind of minor thing.
