Ok,
I'm a 16 year old male I like to exercise and keep fit ( I run 10k twice a week) My diet is not great but has not changed in the last few years and recently i have started suffering from the occasional migraine, maybe once a month, I know this is nowhere near as bad as some of the people who are suffering from them but it is a major inconvenience not just to me, but to my parents aswell 
I drink plenty of water and rarely eat new/strange foods.
Also, before my most recent migraine my eyes felt a little funny, like when you look at a bright light and then look at something dark and I was struggling to focus on things when looking at them.
If anyone has any idea's what I can do to prevent them or even just ease the pain it would be greatly appreciated.
Many thanks,
Logan
i have had a migraine with the aura about 2 yrs ago and then last monday had two in one day one on the wednesday and two on the thursday i went to the doctors and also went to get my eyes tested in between attacks i had strange vision as you have but my doctor and every one else says it stress and anxiety my eyes are ok but i still have a lot of head pain so i suppose we have to try to relax Hope it helps
If the funny vision thing comes before the headache comes, it sounds like you have migraine with aura which I had for about 20 years before I stopped having the aura and started having different sorts of migraine.
I found Migraleve worked for me. You can buy it without a prescription. I used to have difficulty seeing properly and know that a migraine was on its way. There were blanks where I was looking and it was all shimmery so I would have to look to the left or right of something to try to see it. It was very weird.
If I took a Migraleve tablet within the first half hour of having the funny vision then it stopped the migraine coming. There were 2 colours of tablets - yellow and pink. You took one colour when you had the funny vision thing and then a different colour if the migraine had started. It worked so well for me that I never had to take the second tablet.
This might work for you.
Thank you for your comment trudy i have to be so carefull what tablets i take due to asthma and lots of stomach surgey it alarmed me at how many i got in a short space of time i have been told it anxiety and stress due to me worrying about a forth coming operation but many thanks for your comment at least we know there is some one out there sharing there knowledge
