luduplo,

Welcome to NeuroTalk. There is not definitive way to say if you suffered a concussion without doing expensive testing/blood work. The best specialists say that if you hit your head, suspect a concussion. Your symptoms make it sound like you may have suffered a mild concussion.

Insomnia can also cause symptoms similar to a concussion.

Either way, the best way to treat a suspected concussion is with quiet rest. Minimize excitement, minimize sensory stimulation (audio, visual, etc), avoid caffeine, alcohol and MSG. Minimize screen time (computer and TV), especially screen time with quick moving images. Also, avoid physical exertion. 85% will recover spontaneously within a week or so.

If you symptoms continue past a week, let us know. We have more information for you.
