Good afternoon. I can certainly tell that you are not the nervous type if you are willing to write your question out and submit it the way you have. That takes a little bit of courage. There are a couple of things to come to my mind when you describe your situation. One is called orthostatic hypotension or also orthostatic tremors. this condition is one where a person can start shaking in their hands and their knees and their arms and their legs after they have been up on their feet for a few seconds or a few minutes. Usually, when this starts to happen and they sit down the shaking goes away. The other thing is called benign essential tremor or or benign essential familial tremor if the condition runs in one of your family members. however, in this case I would go preferentially with the first one since it seems as if your trimmers get worse when you are standing and writing something. at any rate, you should see a doctor who can take your blood pressure is in different positions such as lying, sitting, and standing and make a determination as to whether not you may have such an entity. would you please rate this answer with a star rating if it meets your approval for what you were looking for. And good luck to you in school.
