Other symptoms include visual/sensory auras. It is, perhaps, the most obvious manifestation of migraines. What do these auras stand for? Well, they are best characterized by the flashing/blinking lights and blurred vision. A person can also see spots in front of his eyes. Some people report on the curves and waves. While some patients complain of the severe headaches, others notice only problems with vision. Moreover, there are times when people get numb with that pins-&-needles feeling, which occurs in the limbs and face.
