I have had headaches for goodness knows how long, but this week its has been none stop and more on my left side. Just above my eyebrow. Yesterday I saw a weird site in my eyes, like a black and white calidiscope which moved as my eyes did. It got progressivly bigger and the middle became almost transparent with the edges becoming sharp and jagged but still the black and white moving continusly. I gradualy fade and now I just have slight blurring in my right eye. I am really scared as I have never heard of this before. It wasnt in my eye I could see it quite far away. Please can anyone help.
