Ever since I can remember (5) I've had these symptoms as though I'm about to faint but I never actually black out. If I'm stood up too long I feel dizzy, sick, sleepy, my neck and my ankles ache, I get hot and sweaty, I got confused and find it hard to speak, my feet and ankles go purple and cold (these are the basics) When I eat I feel extremely sick and sometimes I am sick. I can't do much exercise because when I do I get hot and then dizzy and all my symptoms come on. I then go into a two and a half week period in which I have all my symptoms if I move my head too fast or stand up etc. A couple of weeks before I go into this stage I can't lift my head up to the sky as I lose my vision and it feels like the blood is draining from my head and it makes me dizzy. I've been told I have low blood pressure as I had a tilt test and my blood pressure dropped to 76/16 so I was told I tested positive for reflex syncope however I've never blacked out or fainted. Is this the right diagnosis?
