<s>[INST] I have a slight tremor with my left hand. it s been going on for months and some days it s better than others. I have noticed recently that my forearm seems a little tired also but not all the time. What are some possible causes? I am not on any medication [/INST] Hello, Your symptoms could be related to a pinched nerve. For this reason, I recommend consulting with a neurologist for a physical exam and performing nerve conduction studies. A brain and cervical spine MRI may be needed. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ilir Sharka, Cardiologist </s>
