Everything is always worse at night. why?

And how come its not awful during the day? I mean, I am thankful it is not day and night but why only night?

Last night was awful. Just one of those nights where nothing worked. The burning, hot, pain was unappeasable. Epsoms bath, lotions, fans, nothing seemed to help. Sleep eluded me all night.

Which meant all day all I wanted to do was sleep. i could not get motivated to do a ding, dang, thing. Finally at 2 I fell asleep on the couch and slept till 430.

Thing is, slept like a babe. No pain, no burn, nothing.

Why oh why does it have to happen only at night? :/
