I feel as though at this point I’m developing anxiety. I’m currently taking Propanolol for my high heart rates but I still have a few episodes of it getting into the 120s. The doctors seem to think that something else might be causing my POTS so my mind is always thinking of what it could be. My blood pressure fluctuates a lot from being a little high, to normal, to too low. I’ve learned this is a very difficult syndrome to manage.
