So, it's been about a week now, since she had this, she had to call emergency so they can pick me up at 3 O clock in the morning and then she took CT scan and MRI but no stroke or no heart attack. Right now, she was still, patient had no chills or fever. It had been ok for a day or 2 now but, the vertigo was just about over. She mentioned that most of us like do get it by, she just had it couple of days and little bit down because patient could not remember but her head was just spinning.

So, she was wondering if she should cancel it completely or she should wait to reschedule it.  No follow-up attempts are possible. No further information is expected.
