Ever since my CFS started (more than a year ago), I have also been feeling pressure in my face. And recently, a scan showed I have infection in my sinuses and mastoid bone of the left ear. So maybe this pressure feeling is my sinuses. But here is the odd thing. Up until recently I only felt this pressure when I was standing. More recently, I also feel it while sitting. But if I lie down for awhile, it goes away. And there also seems to be pressure and aching in my legs that happens at the same time. The leg thing makes sense, because maybe the blood pooling there when I sit or stand. But I have no idea why I would feel pressure in my face. Unless is a feeling caused by absence of blood? Because I also get a little spaced out along with this. Is anyone else experiencing this? Or has anyone heard of anything like this?
