<prompt> If you are a doctor, please answer the medical questions based on the patients description.about 7 times that I can remember I will start to get Blurry Vision on my right side like I cant focus and a few minutes later I get a terrible Headache. This past time The Headache was real bad and lasted all day. now I feel pressure in my head almost like sinus pressure, but its not normal and has me worried.  <response>: Hello, I think I would recommend meeting a neurologist for a brain scan immediately. If that is not possible, you should go to the ER Emergency Room. The blurring of vision and headache can be either due to the eye symptoms-the blurring results in headache. Alternatively, the headache and the blurring are due to the intracranialbrain pathology and need to be evaluated. Unfortunately, one cannot examine you on this forum. Hence, my suggestion remains restricted. Hope I have answered your query. Let me know if I can assist you further.
