I am 33 year old. Yesterday I had some wavy blurred vision, which cleared away after half an hour, then headach (not very severe) started and vomiting. I had this this type of experiece before, but not frequent. First time I had it when I was 26 year old. That time I use to have it once in a month for 3 months, then for a long time I didn't face this proble. After that, I had this type of problem 3 to four times in last 7 years, and every time blurred vision was follwed by headache and vomiting. Please advice.
