Dear all.
The cardiologist called and he told me that magnesium oxide stays in the gut, and that I should stop it after it 'has had its effect'. But he then told me that it couldn't impact the heart and wasn't really open for the rest, as I feared. He told me I should go to the ENT for the bloody noses 🙁 No blood test needed and so on 🙁
So since I still have a form to do blood works I will use it to have this checked.
I did not change my diet, nor did I take other meds (I pretty much throw away all things they force on me, taking only the metaprolol retard and perindopril). I abhor medication and would prefer to not take anything at all. I stay away from pain killers too, I mean, as a single woman I have to monitor myself, the cats can't do that, right? So I want to know what goes on, what happens and when it gets better, or worse.

@afrobin so true! I know my body. And doctors are sometimes stuck in their ruts. They have no interest in things that are 'curieux' 😀
I have discovered quite a few things as well, such as coughing very profoundly to stop the ridiculous heavy beating of my heart, especially in my throat. I noticed that I would sometimes start coughing because it was beating so profoundly, and then would cough and this would make it better. And that walking vigorously will calm my heart. And other things, too. I had almost three years of incredible pain in my feet, the doctor wanted me to have special shoe inlays but last year, I decided to do some massage and in only two days, the pain was gone... it only came back once, one day, then disappeared.
