Hello and thank you for your question. There are several issues here. If you were blacking out then it could mean that you lost too much blood and were not getting enough blood to your brain. You need to see a doctor as soon as possible to make sure that you do not need a transfusion. If you were in a lot of pain then that too could make you pass out and not remember things. If you have not had a tetanus shot in the last five years you need to get one of those. Please make arrangements to see a doctor or go to Emergency as soon as possible. Regards
