It is difficult to say what is the exact cause of the symptoms you have described. It could be related to sinus swelling and referred pain. It could be related to the other facial nerves, which can cause pain if inflamed. It is important to get a CT scan of the sinuses to see if they are involved at all. If they are, it does not rule out other nerve pain, but is something to be addressed. If the sinuses are clear, then this gives you an avenue to approach other areas as the primary cause.
I will ask my doctor for the CT scan on Friday.
Now my right eye lid is beginning to droop. On Saturday it was half closed but today isn't as noticable.
Once more I've called the doctor to try to get an appointment or a referral.
