So about 4 weeks ago I woke up in the morning like normal and took a shower. By the time I got out of the shower my heart was pounding. I took my pulse and it was 150 so I sat down. It went down some but when I got back up it started going up again. I decided to go to the emergency room since it really scared me. On the way I got a really bad tightness in my chest. I called an ambulance because I thought I was having a heart attack. Things are just getting worse as the time passes. The cardiologist says my heart is healthy. He does not want to diagnose me with pots for some reason, but put me on florenf and told me to drink lots of liquid and sodium. This is not good because I have no appetite, this started because I was having a tightness in my throat and chest after eating that would eventually go away after burping, but it would take hours some times. I have had GI issues ruled out. Another doctor said it was all anxiety, so I asked why would my anxiety go away just because I was not moving? Apparently it can do anything. I am even waking up with my pulse 150 I originally thought it was because I was moving in my sleep, I realized last night I did not move and it was just the act of sleeping that made it go up. IS this POTS? Can anyone give me advice or help? Even rolling from my back to my side is increasing my pulse, is this typical? Do people still work with this?
