I have a similar distribution of facial numbness - although more recently it has spread to around my eye as well. Actually mostly I forget about my facial numbness until I am in a cold wind, and then I notice the patches on my face that I don't feel the wind, it's weird. My numbness on my face is left sided too. I have a lot of numbness in other parts of my body too.

Google a picture of the nerves in the face, and you will see that neurologically the area that you are describing make sense in terms of where the nerves are.

Have you seen a doctor about it ?

I'm from down under too - I'm a kiwi

cheers
