I took the following numbers from "The Symptoms We Get From Pots" poll. total votes as of 6/1/13 n=110 Symptoms Votes fatigue 96 lightheadedness 92 brain fog 89 Dizziness 89 Cold hands and feet 87 palpitations 86 These were the most voted for symptoms, I am assuming all of us with POTS share these symptoms. Symptoms Votes feelings of panic 64 feeling like you are going to die 55 feelings like there is something else, undiscovered that's wrong 69 feeling like you should be in the E.R. or hospital 58 Feeling like you have to know what your blood pressure is doing 49 Here are some more qualitative symptoms, they may be caused by everything else that is going on. More than half of us suffer from feelings of panic (64/110 =58.18%). As far as I know the mortality rate of POTS is zero. You can remind yourself of this fact if you feel like you are going to die. Symptoms Votes presyncope 81 full syncope 33 Presyncope can be scary especially in public, In my experience it has been a major cause of my panic. I have never fainted from POTS, 30% of us do faint. Assuming that those who faint voted presyncope as a symptom we can gather that 43% of us experience presyncope but do not faint. So if you know that you are not a fainter use this knowledge to calm yourself when you feel presyncope. Personally, I think that panic stops me from doing many things. However,since my diagnosis, a little over a year ago, I have learned to somewhat subdue my feelings of panic. I can say that this has significantly improved my daily activities. Hopefully this helps, also share ways that you have found to calm yourself instead of panicking.
