I'm wondering if anyone can relate to having a weird sensation in the chest that isn't heart palpitations. I get palpitations and with those I can feel a fast beat or a skipped beat etc. The symptom I'm talking about isn't an actual feeling (like I can't *feel* twitching or fluttering or anything like that) but it's just a sensation of... lightness? emptiness? I don't really know.
It almost feels like I've had a ton of caffeine (I haven't) but my heart isn't actually beating fast, skipping beats etc. My heart rate is normal and steady. It almost feels like a breathlessness. It's such a strange sensation and when I try to look into it, everything is about palpitations. But again, I have actual palpitations and this isn't that.
I've had a full cardiac workup over the past 5 years - echo, stress test, Holter monitor etc and aside from benign palpitations they've found nothing wrong. But this sensation continues to cause me anxiety. When I have "flares" of it, it lasts for days. When I'm preoccupied, I don't notice it but when I am focused on it, it drives me insane and continues the anxiety cycle.
I do have reflux and I tend to think it relates in some way to that but it's definitely not heartburn or throat twitching/spasms (which I've also had).
It freaks me out that I have some kind of arrhythmia or something, but I'm sure it's more likely anxiety. Just curious if anyone has experienced something similar?
