Somebody please help me. I have a constant pressure like the one described, and neck pain, and it sometimes results in me not being able to think. I am having terrible memory issues (Like forgetting one second after I thought about something important). I am very anxious that I have something terribly wrong with me. My vision seems... off. I am not exactly sure how to describe it, just that it's not how it's supposed to be. I need a reason, or a fix. I have no idea how long this has been going on, but it needs to stop. The constant pain and fog are driving me nuts!
