What Causes Blurred Vision And Constant Headache?

hello, I was diagnosed with pseudo tumor cerebi in 2012. My symptoms were a bit extreme, double/blurred vision, constant headache. Fortunately, my sister s friend was a neurologist who was able to see my right away. I had a spinal tap done then was put on a prescribed water pill ( diamox I believe it was called) until the doctor instructed to stop taking. Lately, I have been feeling certain symptoms that were prevalent in my earlier stages before the double vision, and am worried it may be resurfacing. I have headaches in the morning and at night, and my headache was extremely worse when laying down. I am just not certain if this is just allergy symptoms or in fact my PTC has come back. Other symptoms: Nausea/ vomiting feeling cloudy/ clogged eyes are extremely heavy feeling lately hard time focusing ear ringing from time to time headaches
