Hello, I believe the most important thing to rule out and fix (if there is a problem) is a thyroid nodule causing Hyperthyroidism which can cause all the symptoms you mention, although we tend to think of endocrinological pathology as the cause to neurological issues in a symmetric instead of asymmetric fashion. But it can happen asymmetrically as well. I would not worry about guessing too much about things and just look at the obvious for the time being. Once, that has been properly evaluated and addressed as needed. If you are still having problems then, go to the next level of the chess board. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Dariush Saghafi
