My head exploded

My head started aching this morning around 10:30 or 11:00. Not the sharp “needle behind my eye” pain I associate with a migraine, this was more of a dull pressure on the temples. Probably more to do with allergies, it’s that time of year after all. Things weren’t any better by 3:30, so I told a couple folks I was going home “before my head explodes.”
I got home a little after 4:00 and stretched out on the bed, thinking that a short nap might help. The next thing I knew, it was after 9:00! My head felt better for a while, but the pressure’s building up again.
On the plus side, I’ll have no trouble sleeping tonight. The “non-drowsy” allergy medicine puts me to sleep every time.
