Hello doctor! My name is Valentina and I am 24 years old. I was wondering if you could help me out with my odd symptoms. As of late, whenever I get a very painful headache, my vision on my left eye becomes very blurry to the point where I can t see. It goes away after a few minutes and while it doesn t happen too often I am very worried. I don t wear glasses and my vision tests have always come out positive but I haven t gone to the optical for almost 3 years.
