From what I've read, vertigo will usually come and go. When you're experiencing constant vertigo, it's suggested that you tell a doctor. What you're describing sounds like vertigo to me. That is one of my least favorite symptoms. Mine was so bad I was vomiting from the dizziness.
I'm sure there is something they can give you to make it go away or at the very least, calm it. For me, I felt the best when I was driving, it was the sitting still that really got to me.
