I used to get migranes every couple of mths or so, usually when i was stressed or overtired. I started getting them when I was about 7yrs old.
When I was about 19 I started getting the "flashing lights" & distorted vision about half an hour before the headache would start. If I took nurofen plus & had a lie down before the headache started I would usually be ok.
Since being pregnant with DD I haven't had one! I was so worried about being pregnant & not being able to take painkillers, but I haven't had to worry
