I've been having anxiety related to my heart health for about 4.5 years now. Last year I've had a bunch of tests done (again) and a cardiologist said that my heart abd blood circulation are fine, all I have is a benign case of premature contractions. This manifests itself in "skipped beats" where my heart will beat normally a few times, then skip a beat and then come back with a strong beat that I can feel as a palpitation in my chest. I am sure many of you here are familiar with these symptoms. But lately I am struggling with a new symptom, which is scarying me and I am doing my best to keep myself from going into another round of tests.
In the last month or so, these palpitations have become more frequent and the worst part is that most of the time I feel them at the back of my head. Sometimes the beats are so strong that I can just picture blood hitting the arteries. In the worst cases it is painful and I can also "see" it through my eyes as I get "vibrations" corresponding to heart beats in my eyes. Sometimes after a strong beat, I get a bunch of sparkles flying around my peripheral vision (the symptom that usually indicates lack of oxygen supply in the brain). All of this usually happens when I am walking, but it did happen a few times when I was doing nothing. I've tried to research this on the internet, but could not really come up with any meaningful explanation except high blood pressure and anxiety symptoms. Well, I've measured my BP many times when having these symptoms and it has been in the normal range. I am fine with the "skipped beats", cardiologist's explanation is ok, it is the feeling in my head that worries me. I just can't get myself believing that this can be caused by anxiety, cannot understand the mechanics behind it, to me it feels like I have blood vessel spasms or something constricting the blood flow and that one of these days an artery is going to burst and I will have a stroke.
I need to figure out how to deal with this, is having a stress test, echo, holter, event monitor and blood work about 8-12 months ago enough reassurance or do I need to check this new symptom out? I hate going to the doctors because I feel like I am wasting their time and causing delays for real patients, but at the same time I need to somehow get myself back together, this new symptom is not letting me excercise or even go for long walks which I enjoy so much, and which helped me a lot with my anxiety these last few years.
