Just updating FMI, I went to a kidney specialist to see if there are any abnormalities with my kidney resulting in my high blood pressure. Now, my left kidney is kinda messed up, it's smaller than the right because of something about it's development when I was younger. Now, it works, but not perfectly, so I had an ultrasound to check the blood flow to it. If the blood flow was restricted or just abnormal then that would have effected my blood pressure and would need to be addressed. However, no abnormal blood flow was detected, so I'm right back to where I started.
Good news (if you can call it that) is that physically I'm okay for now, but I still have the high blood pressure which probably caused my heart issues. Since I've been on medication I feel much better, and my heart has stopped fluttering. I still need to watch what I eat, keeping my sodium and caffeine intake low, but I can live like normal again for the most part. I'm sure more exercise would help, just need to get myself to do it!
