I'm a relatively healthy 30 year old who fainted the other day.
I had been sitting down reading for about 10 minutes when my nose started to bleed slightly (it never bleeds). I dabbed the blood away and next thing I knew I was waking up on the concrete floor with people shaking me (I'm not squimish at the sight of blood). They helped me back on my chair and offered me water. I reached for the glass and again woke up on the very hard floor. I kept fainting at least half a dozen more times over the next half hour. I couldn't even sit up to lean against the wall for a long time. I banged my head up pretty good with all the fainting.
When I got to the hospital over an hour after my last faint, my bp was 74/44! They kept me in for a few nights to run a bunch of tests (they suspected a possible pulmonary embolism), but all the tests came back negative.
- I had eaten normally
- I had drank normally
- I had had a normal day up to that point, even walking for 30 minutes less than an hour before the attack
- I have no other medical problems of any significance
- I exercise regularly
- I'm not overweight
- I had flown approximately two days previously, but it was a relatively short flight (about 5 hours) and I had lots of leg room, had drank lots of liquids and got up and stretched my legs a number of times
I'm scared that this could happen again. Any idea what caused this?
