I ended up unconscious for 30 mins about 3 years back. I got up to use the shower etc next thing I know there are para medics around me, I can hear them but can't speak. David had heard me collapse and put me into recovery position because I had blocked my airway the way I had fallen.
Spent a while in hospital but never found the reason. It was spooky. I could hear the medics discussing a stroke or brain haemorrhage and saying I didn't look good (cheeky sods)
I think it might have been trapped wind.
I have very high blood pressure but it's normally low BP that makes you pass out.
