There are posts if I recall correctly regarding the "cobweb" feeling. I think they relate to parasthesias for various different reasons. The fact that you have no pain is good although you might want to search the forums for that cobweb feeling. It might give some clues. I would have suggested the Trigeminal Neuralgia or even Dental forums if you had pain, but I doubt you can have TN with no pain, but I don't really know about all that. You could search there though. It just seems suspicious it's in one side of face and you had an eye issue as well.
all the best. Do try the search feature at the top of the screen if you haven't already.
