If it is any consilation i have got one too , i have taken paracetamol and ibuprophen together and it has eased but not completly gone.
It could be the weather, i always suffer when the weather changes, again as mentioned above its been my T.O.M and i have had chocolate, and it too has affected my mood and no doubt contributed to my bad head.
