Female, 35 years old, 165 lbs. -Each day around the same time of day I get dizzy, it is hard to focus or concentrate. This last for 20 mins or so and then I get sharp stabbing pain the back of my head and tunnel vision. I was seen for this the first time it happened while I was at work. My vitals were all normal. I was given a shot of Tordol and migrain medication. Since the first episode it has occured daily, which is 6 days now.
