Hi, I am a 34 yo female. I have recently had my third episode of hand tremors within the last 9 months. It has occurred in my left hand every time and usually lasts an hour or two only when my wrist is bent a certain way, and never while resting it. After the tremor has subsided, my entire arm feels weak and heavy, a feeling which also spreads to my neck and face, and sometimes chest. Afterwards, I am wiped out and have no energy, and sometimes have a headache. I am currently working with my doctor on this issue and have even had a brain MRI with no significant findings. I am scheduled for an EMG at the end of next month. I don't understand the intermittent nature of my problem. Do you have any ideas?
