The title explains it all. Those are my symptoms and I've never been to a doctor about it. I'm asking this question here because nobody within my circle of friends goes through anything similar.
These symptoms arise almost every time I take a nap (usually lasting an hour or longer) and have been present for as long as I can remember. I wake up with the pressure, within a few moments feel the headache, and then realize I'm straining my eyes to focus on objects (it's not like my vision goes to crap, I can just tell that it is slightly adversely affected).
I asked this in [r/DAE](http://www.reddit.com/r/DAE) and was told that it's a migraine brought on by caffeine withdrawals but I don't necessarily buy that. I've never had these symptoms when I wake up in the morning; they *only* occur after waking from a nap (usually in the mid afternoon). Also, I rarely consume caffeinated beverages. Occasionally I will drink an iced tea (It's been over two weeks since I've had my last one and I had these symptoms two days ago after a midafternoon nap).
Doc, do you have any idea what this might be? Or what these symptoms might be attributed to?
