Okay so about 3 months ago I went to the ER because I was having chest pains, at the ER they did 2 EKG tests, heart monitor, blood tests, and a chest X-ray. Everything came back normal except in the first EKG they told me I had arrhythmia (at this time i was very anxious) and they second EKG they did was after they gave me some Ativan and I was a lot more calm and that one came out normal. They also told me my potassium levels were low, but as of right now they are back to normal. About a month after that I started getting a lot of heart palpitations (still having them) it feels like a skipped beat, and then a thud. Sometimes they last all day and sometimes they only happen when I'm lying down or sitting. They could be happening anywhere from every few seconds, or every minute. I went to my doctor and she thinks it might be anxiety, but she ordered me a holter monitor (still haven't gotten it I don't know why it's taking so long). But now, starting yesterday I've been getting this weird feeling in my stomach and chest. It's hard to explain but it feels like the feeling you get when you're startled and your heart and stomach "sink". Almost like a nervous feeling, it can also be described as the feeling you get when you see something like a ghosts and it freaks you out for a second. This feeling keeps happening, it happens every minute or so, sometimes a few minutes. I don't know what is causing it and it's freaking me out!!! I have pretty severe anxiety, especially health anxiety. I freak out over my health all the time. I don't really have very many panic attacks anymore (I used to have them allllll the time) but I do feel anxious a lot, and I also worry about my health a lot. I just want answers, is there something seriously wrong with me or is it just anxiety?? Does anyone else experience anything similar??
