Mine are triggered through stress and have no warning. I will start of with a headache and it will progress from there, my last one lasted 14days and I ended up in hospital twice (for just that episode). So i'm very sympathetic when someone says that have had a migraine. (Mine have been called both Chronic Migraines and/or Cluster headaches)

And Dr Oz did a show on headahces a while back... do a google search for "Dr Oz Migraines" and his advice will come up. xoxox

Hope your okay xo
