When i get nervous or upset i start shaking really bad. i start having complete body tremors especially bad with my head.it started almost a yr ago.

Yes tremors do that: All types of tremors worsen when you are in pain, upset , angry or anxious.

Most tremors worsen-: In the face of increased stress, anxiety, fatigue, or caffeine tremors of any sort tend to get worse. Of course, this could also have a psychological explanation as well.Your primary doctor should make a decision as to whether or not they should send you to a specialist or just try some simple treatments on their own.
