The pain only girls know

Guys can skip to the next post when it's out.

Comparable to migraine, there's this pain that only girls know.
It comes and it goes, regular and moody.
With any slight shift, there you have it:
The tightness, the pain, the dizziness, the nausea and the cold.
Shift again, and find a comfortable position.
Rest and it goes off.
And then, you heave a sigh of relief...
and you've moved again
and it's back.
It's horrible.
You yawn, you move.
You try to hug you stomach, you move.
Cramps. Arghh.

I exercise not to lose weight, I exercise to stay cramp-free.
