<s>[INST] I ve had rest tremors in my left hand for almost two years. My neurologist has put me on Amantadine 2x daily and I still have tremors. I also suffer from a rotator cuff injury in my left for a number of years. Could the tremors be the result of that injury? [/INST] Welcome to Chat Doctor I have gone through your query and understand your concern. Tremors is unlikely to be due to rotator cuff tear or injury.  You are likely to be having neurological disease. You can go through thyroid function test as hyperthyroidism can because of tremors. Other causes of tremors can be Parkinson's disease. Anxiety is other important cause of tremors. So you should get yourself examined by physician to rule out all these causes. It is unlikely to be due to injury to rotator cuff tear or injury. You can discuss with your treating Doctor about it. Hope I have answered your query. If you have any further questions then don't hesitate to writing to us. I will be happy to help you. Wishing you good health. Take care. </s>
