Usually I get the super scary migraines (you know the type that make you think you are having a stroke or TIA). Usually I know I have a migraine from the flashing lights (kolidascope (sp?)), numbness in my arm, followed by the headache, nausea, sensitivity to light. Today I just have a headache on my left side of my head. It feels like it's on the total left hemisphere of my brain. It hurts bad, but I had no aura. Because of the location, I'm assuming this is migraine w/ out aura?
