I have recently been diagnosed with migraines with aura and
gravesGraves disease disease. My question is I do not always have migraines with the aura. I am getting the aura, colored, squiggly lines, sometimes prism looking, my vision goes dark, I have a hard time seeing. These episodes last sometimes between 30-40 minutes and other times just about 15 minutes. Many times I have no headache at all after the aura is over. Is this the "norm" with people who have these episodes? Thank you.
