Okay I have been experienceing excruciating headaches since 1997 which I was informed were tension headaches but the pain strikes on one side usually the left and if Im lying down (which is usually when they strike when I wake up in the morning or during my sleep) I cannot open my eyes, my lids feel glued together. it feels like Im going to die, it's more than just dizzy my head is spinning so fast like someone has my head in a vice grip (or plyers) and is flipping me back and forth all I can do is lay there and suffer but sometimes Excedrine Migraine relieves the pain, even if I take a Tylenol pm or something it triggers the headache I usually get these I call them migraines 3-4 times a year is it a migraine or a tension headache?
