so the other day after being up for awhile i had a spinning clear disk shape in my eyesight reasonably large.(hard to describe)everything in that area was spinning but clearish, outside the area was normal lasted about 1/2 an hour. its happened twice. When i used to get the mega killer migranes i never had that, and never during the 2 yrs of 24/7 vertigo until now so was that an aura??? :?
Based on what you describe I would bet a gazillion dollars you had a scinitillating scotoma aura. Click on this link (brace yourself - will make you feel uncomfortable) to see a range of scotomas.
If that doesn’t work just do a Google image search for ‘scintillating scotoma’.
Sounds like an aura to me.
