You didn't tell us the results of head ct and x-rays done at the emergency. And if MRI is for diagnosis determination. Main causes could be inner ear pathologies and neurological problems. These is visits you should have although after RMN results you should discuss it further with your GP. Hope to have answered your question. </s>
