Hi,

2 days ago I was standing on a moving train when the train suddenly jerked and I fell, smashing the tip of my chin on a metal bar very hard from an upward angle. my teeth clanked together, but most of the pain was at my chin area. I was of course a little shaken. I did not however, feel my head get flung backwards.

I am not sure if I have any brain damage from this or not, or whether the symptoms i am experiencing are from something else.

Basically i am feeling rather "out of it", and it feels like i am having tunnel vision and the world around me is.....dim or distant.

the morning after that night i woke up(after about 5 hours of sleep)and felt a little bit of difficulty typing on my cellphone as if the motions were unfamiliar to my fingers.

i was trying to convey a certain message through text but somehow it came out in a weird way.

In the time after that till now I have been doing some weird things, such as going to the wrong side of the counter to collect food and etc. For example I walk there like im distracted and then almost immediately i realize like what the heck am I doing, and then do the normal action again.

This has happened several times as if I am very distracted. However I do not experience any amnesia. Just that I maybe feel a little less inhibited and sometimes act out things that I normally wouldn't do or say to strangers.

How do I know for sure if I have damage?
