I don't really have "headaches" I mostly have severe pressure behind my eyes, temples, and in my ears. I have had flashing lights and once a bad episode of wavy lights only in my left eye side vision ( kinda like water reflecting off of something) I also have an unsteady sensation, not dizzy just unsteady. Seen a neuro and she put me on topomax which has pretty much stopped all symptoms. I take 25mg twice a day. Neuro tried to reduce me to 25mg 1 time a day and after 2 days my symptoms were returning.. I went back to 25mg twice per day until I see her again. Does this sound like migraines even though it's mainly just pressure and not a headache? And I should add that prior to topomax, the ear pressure and unsteady/off feeling was pretty constant everyday.. all day Thanks!
