I ve been having this bad headache since October 2013. My doc referred me to neurologist, who said it a migraine. From what I ve read about migraine, it doesn t fit the description of my symptoms and the medications-Imitrex and Nortriptyline, did not help me in anyway. I have tried Aleve 400mg, Excederin, and extra strength tylenol; none seems to help. My head pounds all the time, and it s worst at night when I lay down. Is this encephalopathy or what? flo
