I'm wondering if it could be an occular migraine. My husband gets them when his blood pressure is high. Mr. Type A personality.
He gets similar eye symptoms, and sometimes his vision is so bad he can't drive. The only good thing about
it is that he doesn't get the headache or any kind of pain with it. Also, now that his bp is better controlled, it rarely happens any more. Good thing since driving is a big part of his job!
