Peripheral vision!!! please help!?

today randomly i lost all Peripheral vision in my left eye i could barley see anything only things in front of me and barely that this went on for about two hours. this has happened before but not so severe it happens about maybe once every 3 months for the past 2 years also after this time i got a huge head ache ,nausea and my stomach hurt. I had a head ache in the left hemisphere of my brain. I would say this time is just a migraine but its happend many time and past times i got no head ache.
