hi,
thank-you for providing the brief history of you.
as you mentioned that you have certain symptoms like
dizziness, weakness and uncontrolled body movements. since you have even undergone an
MRI which has not revealed anything than it should not be a worry. because most of the times MRI scan comes normal when there are no symptoms associated at that particular movement.
Since you have tried with the physician i will recommend you to try
physical therapy.
Certain times when there are abnormal neural activity happening in brain tissue, it may lead to abnormal symptoms like dizziness, disturbance in vision, uncontrolled bodily movements etc which can be controlled by the doing motor exercises.
motor exercises will help to have an active conscious control onto the muscles and also it will help improve the
metabolism and motor functions.
I have met certain cases where the symptoms are same and they got control of their symptoms by regular exercises. As the metabolism is improved it will also help functioning of the motor centers of the brain better. Also the dizziness will reduce.
you can discuss the same with your physician.
with the grace of God I wish you a speedy recovery
regards
