What your experiencing "could" be symptoms of Multiple Sclerosis (MS) or at least vertigo and tremors are some of the symptoms of MS.
Did you happen to have a Brain MRI? If not you might think about getting one.
Both links are from the National Multiple Sclerosis Society. The first is about vertigo/dizziness and the second one deals with tremors.
