<s>[INST] Hello Sir,I m Sharif, age 30, weight 70 . I have been suffering from shivering problem.I don t have any disease. I cannot take any drug , not smoker but I don t understand why my hands are shivering when I gonna work specially when I write something.It makes me very nervous. what is the reason & how can I get rid of this problem. [/INST] Hi,Shariful, At this age this is not common but it seems that due to nervousness you have got this problem. But to rule out any nervous system problem you consult neuro physician. You go for thyroid test for hyper thyroidism. If every thing is ok,do not worry,develop self confidence,remove anxiety about that you get this problem. ok and bye. </s>
