I have had migraines my whole life. About seven years ago, I started having neurological problems...blurred vision in left eye, left-side weakness, tinglilng, and tremors. Totally freaked me out. They checked me for a brain tumor and MS. No answers. No diagnosis, though I had a great neurologist who basically said there is a lot about the brain we do not understand, but I have ruled out all the serious stuff. About five years later, the intermittent blurred vision became more severe, so I went to the opthamologist. She checked my eyes and saw nothing wrong, but bless her soul she asked if I ever had migraines. I said yes and she explained that she thought I was having ocular migraines. I now know that I get regular migraines, silent migraines, ocular migraines and my least favorite, cluster headaches. I am on Maxalt for when the migraines are bad and it is a miracle drug. My triggers are stress, dehydration, hormones shifts, cigarette smoke, flashing lights and roof tar, among others. I am getting pretty good at predicting the silent (non-pain migraine) because I get strong food cravings, fatigue and an overall strange feeling....clearly neurological. It has been wonderful to feel like I understand what is happening to my body whereas before I did not realize what my auras and prodrome were like. Before, it would cause great anxiety. Now I tell my husband what is happening at I can take a break to rest and take care of myself.
Good luck!
