Just wondering if anyone has experienced anything like this... a few weeks ago I got really dizzy whilst sitting in my bed I felt real panic like I was going to faint. I've had nothing for a couple weeks and then it happened again when I was driving. I had to take deep breaths. I'm thinking are these panic attacks?! Or is there something wrong with my heart. I get palpitations occasionally mostly at night.. over the past few days I've noticed my right foot and ankle slightly swollen (which I've had before and it usually goes away itself) I am very overweight 😑. Last year I had an ECG and the dr said everything was great apart from my heart rate was fast... are these maybe two separate issues... I don't really want to trouble the Dr at the moment..
