Hi Amy,
Welcome.
I have had tremor as my very, very first symptom. It was visible to the doctors, but it still took me three years to find out why I had it. I had it in a few places. Each doctor would call it something else. We didn't have MRI's back then, so it was a ruling in/out process of other diseases and tests. Then I had other symptoms, went into hospital and was told I had MS.

This link might help you. Good luck
Lady
