geoffreyowens,
It sounds like your tumor is now large enough where it's pressing pretty good on your facial nerve, which may be why you are now feeling numbness or tingling in your face. I had the same issue prior to my surgery 6 weeks ago and in fact I had noticeable facial paralysis prior to surgery. As far as your eye being blurry, you are likely experiencing some minor paralysis in your eyelid not closing well due to the same paralysis issues. Your eye is drying out and causing the vision issues. I'd suggest you start putting in Refresh non-preservative eye drops in every hour or so to keep the eye from drying out. You don't want to have a scratched cornea for sure! Be sure and ask your ENT about this matter when you visit with them. I've been doing this since prior to surgery as I had and still have facial paralysis due to facial nerve damage caused by my tumor. I also apply Systane eye gel at night and tape my eye shut to keep it from drying out. I'm having an additional surgery this month to put a weight in my eyelid so that my eye will close naturally.
By the way, I didn't have too much issue with headaches prior to or after surgery, so I can't comment on that, but I think it's pretty common stuff. My overall advice about what you are facing, the dread is likely worse than the reality of what you are about to go through....
