Hi Hometownglory,
If you've been having headaches since Friday, and bearing in mind you passed out too, i would call your doctor immediately for an appointment, to which he may refer you to hospital for checks, or just go to A&E now, and tell them what happened. They may carry out tests on you to see if any damage caused. Also odd that you cant remember anything too.
Why have you left it so long to do something about it?
Get it sorted out, so you'll have peace of mind.
Best of luck to you.
