Hi Rhonda, I also experience tremors to varying degrees. They become much more pronounced if I am up and walking about, if I am extra tired, have over-exerted, or have not been drinking enough water/taking enough salt. Sometimes I have the full body shakes, sometimes it is just my hands. I was on Midodrine for a while and did not notice any specific increase to the tremors, but everyone responds differently. I would think it may be more in relation to the TTT and may take a bit to settle back down. My BP doesn't drop either, it elevates and my heartrate is around 170- 180 as well, so we sound a little bit similar! I wasn't told that I did not have typical Pots, I'm not sure what your doctor meant by that. As Morgan said, I don't think there is really a "typical" form of Pots. We are all pretty individual in how this affects us. Hope some of this helps you to sort things out. Janet : Welcome to the site! Hope you get some good info here and meet all the great people.
