I have occasional ocular migraines. Started using the Zicam swabs and I've had two today. That has never happened before. My migraines start with kaleidoscope vision and are followed by intense pulsing migraine pain. It feels as though someone has taken my eyeballs out and used them for bouncy balls before putting them back in. Needless to say, I won't be taking Zicam any more. Thanks so much for this board.
