[QUOTE=Drifting;895058]... Also, I often have a strange feeling in my forehead. Like someone or something is pouring cold water under my skin. This feeling usually comes after bad headaches.
Those are my uncommon symptoms.
That kinda reminded me of the ol' brain freeze from eating ice cream type of headache... wonder if it's related. Constricting blood vessels, temperature regulation, that kinda stuff...
