Answer:
It doesn't necessarily have to anxiety. Based on what you said in you question "I know I ask a lot of medical questions" it seems that you worry a lot which can cause this to happen. I know this might sound funny but I know a lot of women who are always shaking and cold. I couldn't tell you what the cause of this is though. Another thing is, do you take in a lot of caffeine? This will also cause these symptoms
Yeah I do. It is weird but not bothersome to me. It usually happens when I am nervous or cold.
Do you ingest a lot of caffeine and sugar? Lots of caffeine can have a negative effect on your body - I know that if I have too much, I get shaky, dizzy and nauseous. Are your heart and breathing normal? I'm assuming you've had a complete checkup. You may want to keep looking for new doctors until you find one that knows what's wrong.
