I Have Been Getting Migraines For Some Time Now, Maybe

I have been getting migraines for some time now, maybe a couple of years. Anytime I get them it feels like the migraine is right behind my eyes. Today a short while after I woke up, no longer than a hour and a half later, I began to have distorted vision, like waves, in my peripheral vision. When I looked it up online I got an answer to a question close to mine saying that it was called ocular migraine. Usually no pain. There was no pain during the distortion which lasted briefly, maybe ten or fifteen minutes. About thirty minutes after the distortion ended I got a slight headache, but not a migraine. Then, after that ended for the rest of the day EVERY time I stood up, no matter how slow, my head started throbbing, not right away but after about five to ten seconds after I stood. What is going on. Should I be concerned about something in my brain?
