I think thats what they are anyway. I ofcourse consulted dr google and it seems like what it most likely is. It only happenes in my left eye. But when I am very stressed I get theses blurry shimmering lines in my left eye. It normally starts on the bottom and I hardly even notice it but then it works its way up right into my line of site. It doesn't happen super often, maybe once a month give or take. But when it does it scares the crap out of me. It usually goes away within 10-20 mins. But those 10-20 mins are pure hell of being convinced that I am going blind or having a stroke. I just had it happen today and now I am obsessing about it. I read that the best way to prevent them is to manage stress and blah blah blah. Which is easier said then done when youre a health anxiety sufferer ontop of every day life worries. Anyone else deal with this or have any advice?
