It usually starts off small and then gets bigger untill it is completely out of my vision and last around 30minutes. When I describe it, people say it could be the start of a migraine, but I never get any form of headache when this happens and in fact have never had a migraine at all before. I mentioned it to my doctor before and she told me it was nothing to worry about but probably worth getting my eye checked because it could be related to eye pressure, however when I had an eye check I was told it was more likely to be related to blood pressure as it is something which is triggered by the optic nerve (although my blood pressure is fine). I dont know what is triggering them but I just find it abit upsetting as I dont know why i get it!! I had it today for the first time in about 3 months - Just wondered if anyone can relate and give me some help?!!
