Hi there, I'm a 19 year old lad that's starting to get a bit worried about my health. About a year ago I started to get a little bit dizzy when I stood up too fast (no biggy, it's quite normal for someone of 6ft). The dizziness slowly got worse and worse but was still nothing major up until two months ago. Then I had my first black out. These black outs became more and more frequent. I should add that symptoms only ever come when I stand up or stretch. Sometimes if I do not pass out, I either get extremely confused (I don't even know my own name) or just a little light headed. I went to the doctors about it a month ago and they diagnosed me with a heart murmur that I didn't have as a child. A week ago I blacked out after standing without warning (usually I can feeling it coming and have a second to take a knee) and banged my head (chipped my tooth too!) on a table. My parents took me to hospital as I was talking a bit of rubbish after it happened, they ended up keeping me in for a couple of days but found nothing wrong with my heart scan (ultrasound), nothing untoward on my 24 hour trace and my bloods were clear. I've got an appointment with a cardiologist at the end of November but my symptoms are just getting worse. I'm passing out 1-3 times a day now and my confusion is the worst it's ever been (just ten minutes ago I was on the floor and screamed because I didn't know what was going on). I'm just wondering if anyone here has any advice on what to do or what might be the cause of this?
Many Thanks, Kieran
