Possible severe brain injuries are NOTHING TO MESS AROUND WITH!!!!! CAN YOU HEAR ME YELLING AT YOU????
Get to a Neurologist ASAP...... If it turns out to be nothing, it's no big deal - BUT ,,,, IF IT TURNS OUT TO BE MORE SERIOUS - IT COULD CHANGE YOUR LIFE......
I have a very good friend, himself a doctor, who failed to heed this warning - especially with "strange" happenings, like confusion.
His daughter died at a very young age!
Get to the Doctor, immediately.
