I am your exact same age and have exactly what you described except for the potassium levels. It really sucks. It's weird to realize that most people out there don't feel their heartbeat constantly, because it's been a background noise almost my whole life.
Yeah, my potassium is not constantly low. It's great and sad to hear that there are people out there with similar issues. I also feel my heartbeat effectively all the time. Caffeine makes it worse, so does alcohol. I stopped drinking alcohol, it made it a tiny bit better.
When I experienced somewhat similar symptoms, I ended up stopping to consume any caffeine (was mostly tea for me), and significantly reduced sugar - and started feeling much better.
Other things that helped was regular exercise, with good cardio load, and getting enough sleep.
Hoping in God and the eternal life definitely helped with the anxiety part.
Aside from VESs; isn't a strong heart beat that you can feel (and sometimes hear if someone puts their ear to your chest) a sign of a healthy heart? I'm not talking about fast palpitations, but rather feeling your heart through your chest wall, albeit at a regular, steady rhythm.
For the most part, your mind will tune out the regular, "background" rhythm of the heart. When it deviates from normal, or if you have certain special sensory differences to regular people, it makes you aware of it.
But normally your mind should tune it out unless you focus on it.
Not so sure. Palpitations are often nothing serious, but what I heard is that not feeling your heart beat is normal. Except when you exercise hard. I feel my heart pumping when I lay in bed an my pulse is 60-70 bpm.
I've been told otherwise by a doctor (not a cardiologist), and I've always wanted to know a definitive answer on this but it's hard to find information on the subject; almost all literature is focused on the rate of heartbeat, not on the loudness of the drumming itself.
