I was diagnosed with paroxysmal atrial fibrillation 2 1/2 years ago. I only take metoprolol on an as-needed basis. Recently I have been experiencing dizziness, strong pressure behind my eyes, and some blurred vision; not sustained; very short episodes. It could be sinus related. I could have sworn that someone on this site stated they were having unusual pressure behind their eyes, that their wife thought it was sinus-related, but that it was something related to afib. Can you assist me as to where I should go to locate this information? I know there are so many posts regarding various issues that you may be unable to help me. Thank you for whatever assistance you are able to give.
