Has it settled?: Flasher/floaters and vertigo (sensation of movement) can be a feature of neck sprain/whiplash. However depending on the nature of the injury may need to think about head or eye trauma although this may have been checked originally. Without having this information, the safest thing to do if any doubt would be to consult a doctor licensed in your area you might need repeat examination. Good luck

May be vascular : This may be vascular briefly due to brief decrease blood flow
