Hi, thanks for writing to HCM.
Shaking in the legs (tremors) suggests a Neuromuscular disturbance. Tremors in legs are caused by numerous conditions like Central nervous system
problems, Parkinsonism, Anxiety
, side effects of medicines etc.
So, a detailed clinical evaluation is necessary to diagnose the exact problem.
I suggest you to consult a Neurophysician for further evaluation and management.
Hope this information is helpful. Good day
