i suffered a concussion 5 days ago, i hit my head off the bathtub after i fainted. The day after was fine, no real symptoms. but since them i am getting troublesome symptoms which include being VERY confused, feeling "not right" have extreme anxiety (had a panic attack), feel nausea, feel foggy, no appetite, etc. Im full of fear and feel like im about to die to be honest with you. i went to the emergency room and they did a cat scan and said it was normal. i was shocked, the way i feel does not seem normal at all. I guess im kind of surprised as to why days after the concussion i start to get these AWFUL symptoms. My sleep is definetly messed up too. has anyone ever experienced this and how long will i be suffering?
