IDK if my info will help but I guess it couldn't hurt .
If I have a really bad panic or anxiety attack I will shake , once in a while I will have a spasm or tremor but I believe that is just really bad stress /anxiety

When I wake up in the morning sometimes I will have uncontrollable shaking but once I'm up and about it stops... I think in my instance I may be over medicated from night the before's sleeping pill. I am starting to cut back on the pill to see if the shaking stops or lessens.

If you are taking medications you may be having a side effect. You might want to just get checked out and have that peace of mind. Take care
