This happened to me a week or so ago - and for the same reasons. I stubbed my big toe on a kerb whilst out walking and then started to feel faint. I sat down for a while and when I thought it had passed I got up with my husband supporting me, but I passed out. Apparently I had my eyes open and was passed out for about 30 seconds. I felt ok afterwards, just a bit tired so just relaxed. It freaked me out too though - and my husband!
Hi!
What you suffered from is probably a vasovagal syncope or a vasovagal attack. The complex group of symptoms are mediated by the vagus nerve. This nerve is irritated by prolonged standing, standing up suddenly, stress, pain, hunger, dehydration, intense emotion etc. It is also irritated by suddenly stubbing your great toe or your elbow. Normally, the attack triggered by stubbing of toe will not repeat itself. If however it does, then you will need a tilt table test, holter monitor, echocardiogram etc for confirmed diagnosis. Discuss this with your doctor. Take care!
