I've had migraines for 15 years or so and about a year ago I started smelling cigarette smoke when there was none, which also is my main migraine trigger, that, artificial sweetener, and perfumes. Oddly (and thankfully) enough the "fake" cigarette smoke smell does not cause a migraine.
I went to my neurologist and had tests done to find out I have abnormal activity on the left temporal lobe of my brain and causes "silent" seizures. It is affecting my memory and quality of life. He prescribed Oxcarbazepine which worked for the first year and now I am smelling it again so we upped the dosage and it's not working this time. Just curious if anyone else has experienced this??? Thanks!
