Scary dizziness- please help!

[hillflower]

Hello, so for the past 4 months, I have been experiencing dizziness (sensation of rocking movement like on a boat or gyroscope). It comes and goes ,but I notice it more when eating and  using the bathroom. It is very frustrating and scary that I have had it for so long. I have had occasional pressure in my teeth and face and have heard a whooshing sound in my ears before..Additionally, I have also been experiencing a buzzing in my left foot. 1 year ago, I had and MRI which came out clear (but I wasn't having these symptoms at the time). I went to an ENT and he said that the type of dizziness I describe doesn't sound ear related (though I am going to have dizzy tests done) He did mention the name vestibular migraine (which I know nothing about) .. I have a neurologist appt in a month and am terrified of getting bad news. What else could be causing this type of dizziness. Does it sound like  a migraine? I am terrified of something like MS..Please help!!!
