i just had surgery july 28, went home august 1. the surgery went well & my recovery has been phenomenal...BUT (there's always that, eh?) i am with you about the facial numbness. mine comes & goes in location & severity. i am trying different things to see if they help. for instance, i spoke with the ENT at the OSU medical center this past saturday, when suddenly, within an hour i regained all of the total numbness that i had right after surgery & then some more! so, yes i spoke with the on call ENT, hoping this was normal & apparently it is. HOWEVER, my doctor (dr. b welling from OSU, that's ohio state univ) is doing a research/clinical study using anti-virals. long story short, they may help stop late-onset facial paralysis, muscle weakness, & numbness. last thursday, at my 10 day check up, he took me off of this anti-virals b/c they were giving me a rash...2 days later, within 1 hour, more than half of my face was totally numb. so i was told to go back on the anti-virals (who cares about a measly rash?!) & i am now regaining feeling & having less numbness.
also, the ENT mentioned that sitting/laying in the same position for a long period of time can gather fluid & then when you move, the fluid shifts, putting or taking pressure off the nerves, which would cause them to suddenly spasm, so to speak, & give more numbness.
i dunno if all this is making sense, i'm no doctor here...but it IS good to know that others have gone through this & even though it may take a few months, the numbness will get better & maybe even go away indefinitely.
i hope this helps...
