Hi. I m a 33 year old female who 8 weeks ago fainted in work whilst having a migraine. This has happened before so I was not that concerned. However, roughly 4 weeks later, I fainted again. This time no migraine. I assumed due to it being around my period, it was due to that. However the last two weeks I ve had constant headaches at different places on the head. I ve been constantly dizzy and on times almost fainted. I ve been to see my doctor who s sent me for blood tests and an ECG. All tests came back fine. He did say my blood pressure was low but it always has been so didn t think that would be anything to do with it. I ve suffered with migraines for about 6 years but never had headaches or dizzy spells as bad as this. For the past 4 days I ve nearly blacked out every day and the back of my neck and bottom of head feel like there s loads of pressure. This feeling of nearly blacking out happened in front of the doctor and he said that it could be because the room we were in was really warm, that I was dehydrated. He also said that I maybe suffering with vestibular migraines. I ve looked up the condition and the blacking out every day and I m still not sure that this is what I have. I m concerned about the headaches and the constant dizziness which has just appeared all of a sudden.
