I have the Aura without headache. I used to have Migraines, but not anymore. I have had the Aura for years. I know when it’s beginning & I know what usually brings it on. If I am on the iPad & also watching TV at the same time, it will start. Also, bright flashing lights can bring it on. I take my med right away & within 20 min. or so, it has gone. I carry the med with me all the time, just in case. It has happened at other times out of the blue, but I am prepared. See your doc & maybe he can prescribe a med for you. My symptoms are not being able to focus or see & bright flashing & zigzag lights appear. I cannot read anything during this time. I usually just remain quiet til it all passes
