I clocked up another passing out incident on Wednesday. Over the years I have passed out on two and half previous occasions. Wednesday’s was the weirdest yet given that it came more or less out of the blue while I was in the office sat at my desk. I felt a strange chest pain, and then started feeling dizzy, and that was it.

It was also strange to pass out in front of the boss. He was just over from the U.S. so I hadn’t seen him in a while. As usual I came to with a curious feeling as if I was coming out of a long dream. …and there was my boss talking to me. I sat myself up and then promptly passed out again. Then I remember dreaming about this weird situation where I had passed out in the office in front of my boss, and I came out of the dream and realised it was true. This time he told me to stay lying down until the ambulance arrived.

The ambulance crew reminded me that raising your legs above your head makes you feel a lot better when feeling faint (The same trick worked well on the ski-lift occasion)   When I got to A&E they probed and poked me, and measured my blood pressure many times. Chest x-rays and heart scans all showed up normal, so it all remains unexplained.

Rather worryingly though, I still have a painful tightness in my chest which gets worse during exercise or exertion. Age 29, a heart problem seems unlikely. Hopefully it will turn out to be some kind of temporary digestion or breathing problem.
