I have been a migraine sufferer from the age of 15 - I am now 63 and have constant weekly sporadic attacks. After many years seeking help from experts I just accept that I will never be able to avoid an attack as my migraines are usually triggered by pollen and dust to cheap perfume and diesel smells. I have cluster attacks / ice pick headaches but have recently suffered a horrendous thunderclap attack which came on out of the blue and knocked me to the ground. My GP suspected a brain haemorrhage which was incorrect - needless to say I can now add this to the long list of pernicious attacks - anyone out there had a similar experience?
