Pounding headache

I am having a pounding headache and I could not function. Well, I am on the last days of my red visitor. I was spared of the premenstrual symptoms like migraine but it is attacking right now. Or is it because I tested the rains yesterday if it would affect me at all. Yes, I went outside without umbrella. I forgot to bring one on my way to the office. Oh, what is it with this rainy December? Anyways, I hope that this headache will go away soon. Paracetamol? I am too lazy to take one. I do not want to turn to it all the time.
