I had a restless night, sweating a lot and tossing and turning. I got up at 7.30 to make a coffee and within 3 minutes of being up my head started to feel very fuzzy, I started sweating a lot and thought I was going to throw up. I grabbed hold of the side of the sink aiming to ease myself into one of the kitchen chairs but the next thing I knew I was waking up on the kitchen floor, struggling to wake up actually. I managed to sit but felt very much like I could go off again at any moment. Sweat was literally streaming off my face and torso. I called to dp who got up and tried to give me a glass of water but I was so confused I couldn't even speak to him. He got me onto the sofa and made me a very sweet black coffee and within a couple of minutes I started to feel a bit more normal. All day though I've felt spaced out and not with it.
I did go along to A&E to check myself out as I walloped the back of my head when I fell and I wanted to check it wasn't anything horrible that caused it. They did an ECG, blood sugar test, blood pressure, neurological assessment, urine test, basic blood tests for infection / anaemia and a chest x-ray. All of these were totally normal except for my low blood pressure (it's always low but it was lower than normal).
They couldn't give me any reason as to why this happened and I wondered if anybody else had experienced anything at all similar or had any ideas. I don't know whether to worry or not, this has never happened to me before. Is passing out always due to something serious? Is an ECG enough to rule out any underlying heart condition?
