Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You should have an imaging study performed of the head (which I m sure the ER probably did: CAT scan, likely in order to rule out a bleed or mass lesion). Now, what might be helpful would be an MRI of the brain to look for other types of structural abnormalities such as elevated intracranial pressure or a Chiari malformation. Unfortunately, until you see the neurologist and have a full neurological workup you will be wondering what is going on. The fact that the ER felt it was ok for you to go home tells us that in their opinion there was nothing seriously going on in the head requiring hospitalization. Now, the trick is to get a rapid appointment with a neurologist. If you were in the Cleveland, Ohio region of the United States we could make that happen. Hope I have answered your query. Let me know if I can assist you further.
