Hello. I've been diagnosed with migraine not too long ago. I get aura before them, followed by severe headache, vomiting (Once and sometimes twice) and unsteadiness. My auras so far include: 1. A crescent in the top left corner of my field of vision. Colourless and blurry. 2. A semi-circle with lines in. The lines would move down it, more lines appearing at the top when lines dissapeared at the bottom of the shape. 3. A VERY big crescent in the right of my field of vision, colourless with eyes open, but, when closed, had zig-zags and was rainbow coloured. 4. A HUGE blind spot, curved, which moved in a way similar to when the TV has no signal. (You know, when it goes grey and makes that horrible noise.) I was wondering if anyone else got these auras? (Especially number two.) Thanks. Oh, and sorry if my spelling wasn't top.
