Actually, you do. Otherwise it's a hypothesis and not an actual diagnosis. Only a CT scan can confirm concussion and the severity of said concussion. Nice try though. A little common sense and maybe even Google could have spared you the last comment. ;)

YES YOU DO and you most certainly need a doctor. Nice try though honey. It's called Google. Use it. Oh,m and common sense as well.

She didn't have a concussion. It takes a doctor and CT scan to diagnose such things. Unless Gaga's hair and make-up artists have PHD's, she prematurely and dramatically announced this to the fans for sympathy and to be a martyr. I love her, but the girl obviously loves attention and will say or do anything for it. I know I will get hated on for this, but it's still true. The truth hurts sometimes. And no, I'm not a little monster. I'm just and subjective fan. Deal with it.
