Increasingly over the last 9 months to a year have had worsening and change in my migraines and felt more nauseous and dizzy. In the last 3 months I have had over 15 episodes of LOC, before falling unconscious i feel hot, sick, vision and hearing goes, last for 3-5 minutes, awake not realising the passing of time, with a worsening head and 3-4 bouts of vomiting and fatigue.
