OK I've seen others weigh in but I will too. Sounds like you sustained a concussion imo, enough to get checked out. In any case it would be very good if you can determine the cause of fainting and try to stop it occurring. It's very dangerous. Here's a reality check story: My mother's musical partner died from fainting in his kitchen because he hit the lower back of his head on a counter edge as he went down. In just a certain way that it killed him. So please take it seriously!Im back. Yes I passed out and fell and hit my head so hard my hubby heard a loud thud and I woke with a headache. Had to take some aspirin to get rid of it. (yay spell check)
