Because that's how my head's felt since yesterday evening.
Tale end of the cold seems to be dragging on and on, and now my head is pounding, feels pressed against my skull and it is throbbing (presumably blood flow). I've had headaches and migraines before and not had the same sensation at all, it's really weird and hard to describe - sort of fluey aches and pains but JUST located in my head.
I'm sure it probably isn't a swollen brain, because although I feel ill, I don't feel that ill and I guess I would probably be in a much more serious condition if it was!
However, I'm curious... I thought you didn't actually have any nerves in the brain tissue itself, so what am I actually feeling? And is it worth seeing the doctor over, or would I just be one of those annoying people who clutter up the surgery just because they've got a bit of a cold?
