Specializes in Nephrology and Dialysis

If neurologist does not detect the tremor and your brain MRI is normal you have nothing to worry. However, if tremor is also noted by the neurologist but he can't make a diagnosis, you should seek a second opinion. Take care and good luck!

A focal unilateral tremor would be secondary to a lesion affecting a focal area of the brain. For example, if the cerebellum has a small stroke, the tremor will be on the same side as the infarction. If your neurologist is "unsure", seek a second opinion.
