Hello @margesil, I know what it feels like to go down the Google rabbit hole trying to figure out what might be going on. I haven't experienced the facial numbness as part of my neuropathy but I have following a few dental appointments so I know it has to be an awful feeling out of the blue. You might want to scan through a few of the discussions on facial paresthesia to see if any are similar to what you are experiencing. Here's a link with the search results that shows the discussions and comments on the topic - https://connect.mayoclinic.org/search/discussions/?search=facial%20paresthesia%20.
