Just because you don't think you have a neck injury does not mean your body is not responding to a neck injury that has no noticeable symptoms. Inflammation in the neck can cause nerve dysfunction. I have had carpal tunnel syndrome for over 20 years. It gets worse when I have strained my neck, upper back, shoulder and / or elbow. There are many ways to trigger nerve dysfunction.

I get hand tremors from time to time. They increase with stress. I can have hands as steady as a neurosurgeon then not be able to hold steady for every day functions. Just trying to remember the times when my hands commonly tremble caused my right hand to have fine tremors.

I can usually relax out of the tremors.

My best to you.
