Hi Doctor. I have ocular migraine issue from childhood. Last migraine occurred to me was in 2009 and before that it was in 2001 to be very precise. I observe that whenever I have nasal congestion I get this migraine attack. Past week I had got one such attack after 7 years. I remember, when I was 12 years old, I visited one eye specialist with my father and he gave me eye drop which helped me a lot immediately. From last 3 days, I have a very mild headache near my eye area. And I am still able to see clearly but whenever I get this mild headache, I get a little blind spot which goes in certain seconds. Today I am feeling almost 99% fine but still want your suggestion. I want to know that Eye drop which had given me immediate relief.
